Medial

What is the medial aspect? -- HJH User:0 15:43, 25 February 2002

• From Kidneys:

Kidneys are one of the most important organs of the body. A pair of kidneys lie in the abdominal region. The kidneys red apple

n-shaped structures. They consist of nephrons, individual units. Each nephron consists of Bowman's capsule, which includes glomerulus, comprising of afferent and efferent arterioles. this is followed by proximal convoluted tubule, Henle's loop and distal convoluted tubule, leading to the ureter. the uerter leads into urinary bladder where the urine is collected and stored temporarily.

• my booty, filtration, absoprtion and secretion, taking place at the glomerulus, henle's loop and distal convoluted tubule respectively, the kidneys produces urine which needs to be excreted as it is toxic. User:Mav 22:34, 23 July 2002

This is wrong: "kidneys weigh about 150 grams. Kidneys are 0.5% of a person's body mass". This would lead to a person weighing 15 kg (33 lbs), or 30 kg (66 lbs) if the first statement refers to individual kidneys and the second to their combined mass. I'd suggest to either strike this or replace it with a verifiable (preferably footnoted) figure (which I do not have available, or I'd do it myself). - André User:194.95.179.131 09:50, 15 November 2006

Just a note in the Plasma Volume section: "A lack of water causes the posterior pituitary gland to secrete antidiuretic hormone, which results in water reabsorption and an increase in urine concentration." It is an increase in the osmolarity of the blood, detected in the hypothalmus, which causes the release of ADH, not simply a lack of water (assuming it refers to plamsa volume?). A large hemorrhage would not cause ADH to be released. User:68.147.130.238 05:07, 30 March 2007

Who has kidneys?

Does someone know which groups of animals have kidneys, do all vertebrates have some? Of course I'm not only asking for myself, this should be added to the text. :o) Aragorn2 17:30, 20 Sep 2003 (UTC)

To do

1. write more about kidney dialysis machines, they are very relevant to this type of article. I did not happen to see them being written about anywhere else, so i think it is appropriate for them to go here.
2. someone to write up more on the structure and function of each part of the nephron
   • IMO, this belongs at Nephron, where, incidentally, most of this information can already be found. --David Iberri | Talk 23:29, Nov 4, 2004 (UTC)
3. more detail on anatomy of the kidney
4. physiology of the kidneys (e.g. control of renal function, control of pH and so on) - can be folded into structure, I suppose
   • You mean renal physiology? --David Iberri (talk) 21:42, 15 May 2006 (UTC)
5. include information on non-mamalian kidneys
6. animal kidneys as food. --84.58.42.75 06:49, 17 July 2005 (UTC)
7. much better diagram - one with readable labels --GrimRC 86.4.53.107 14:57, 29 May 2006 (UTC)
8. Kidney development, more than likely a separate article.
   • Done, but more details are needed. I agree that a separate article is necessary. --David Iberri (talk) 18:38, 6 December 2006 (UTC)
     • There is Kidney development, but it's pretty rough. --Arcadian 05:36, 7 December 2006 (UTC)
       • Blast, I wish I'd looked for that first. :-) I'm trying to address WP's lack of embryo coverage, so I'll see what I can do with the article in the next couple days. Thanks for pointing it out. --David Iberri (talk) 05:39, 7 December 2006 (UTC)

2. Steak and kidney pie isnt made from human--203.53.201.11 01:38, 31 August 2006 (UTC)

Indeed well prepared kidneys (I think from cow or pig) are good food. Neccessary step is to cook them for hour or so to get the taste of urine disappear - there was some specific cooking term for this process. There is finnish traditional food "Karjalan Paisti" - roughly "Karelian steak" wich is meat soup with liver, kidney, heart, and normal meat.

Well it took almost a year but I came along and added a little section on Kidneys as food. -- 125.238.58.85 08:15, 17 December 2006 (UTC)

When I was a kid on the farm, we used to stew beef heart and kidney together in water, onions and seasonings. We sliced the organs into bite-sized pieces, and simmered them in a covered pot of water for approximately one hour, adding a little flour to make a gravy. I still see these items in some local groceries, but have not eaten it in about 20 years. The meat does not have a pleasing aroma as it is cooking, but it has a very pleasant flavor.--Inspirationalpoet (talk) 16:49, 14 September 2009 (UTC)

What about the number of kidneys

I was born with one [left one, not horseshoe] and no problems so far. Can people have more than two? It doesn't seem like the number of brains or hearts varies much. Or bladders for that matter. Why kidneys? User:216.211.25.5 00:59, 31 May 2006

Well I've never heard of more than 2 kidneys in humans, but if you look at all the people donating kidneys you'll see that the remaining kidney can function quite well by itself - as I'm sure you're aware. The other one will compensate to a large degree. I think you'll find that this is the reason why people can vary in their number of kidneys - 2 kidneys aren't essential, 1 kidney is essential, 1 heart is essential, 1 brain is essential -- Serephine ♠ talk - 13:22, 19 June 2006 (UTC)

More than two kidneys can occur in humans I believe...just let me look through pubmed for a source. However, I recently removed a line that stated that same fact because the source that was given was a russian tabloid. If I find the source, I'll add a line about it. Vihsadas 17:30, 17 March 2007 (UTC)

Damage, protection

I think I'll add a little note about the kidneys being prominent _targets in martial arts. --GenkiNeko 18:19, 20 November 2006 (UTC)

... on second thought, I can't see where to insert such a note. Hmm. It -is- a significant aspect of the kidney (the term "kidney punch" is one I'm sure we've all heard), but I'm not sure how to best note it within the present structure. --GenkiNeko 18:22, 20 November 2006 (UTC)

We know that one kidney in us is ok but what can happen from having a damaged kidney in the body? Infection? Lots and lots of pain?

Adding a line about the idiomatic expression 'kidney punch' would be fine, but since the kidneys are retro-peritoneal organs, they are very heavily encased in back flesh and fat. They are located high up and the top is protected by one rib. All of these factors make kidneys very, very hard to traumatize by blunt force. I would imagine that the idiomatic expression 'kidney shot' is more just an expression that doesn't have much physiological merit. -- Vihsadas 17:32, 17 March 2007 (UTC)

If blood from the heart did not make such a short trip to the kidneys it wouldn't be a weak spot. If a kidney ruptures it's really bad. Say someone had a few rerouted arteries so a damaged kidney would not be an immediate threat to the poor guy's life. Would his urinary system still work fine with the lower blood flow?

What you say is true, the blood does make a short trip to the kidneys. However, the blood makes a very short trip to the aorta, and the lungs as well. Would they be weak spots as well? :)

Kidney rupture is infact a serious condition, however, the likeliness of this happening due to blunt force trauma by punch is not high. In other forms of trauma (car accident, puncture wound, etc.) I would imagine that this would be much more common.

Blood flow to the kidney directly affects the filtering capabilities. If blood flow is reduced, GFR will be reduced, and therefore overall kidney function would be reduced. However, if the scenario you describe only happens to one kidney it would not be serious at all. There is an IMMENSE amount of redundancy in the volume of liquid the kidneys filter. (150L/day!, that's like 15 times your TOTAL blood volume!) So, rather large reductions in GFR have no real effect on the plasma cleaning capabilities of the kidneys. Vihsadas 06:23, 26 April 2007 (UTC)

Gastronomy

I agree with one of the previous comments : this excellent article needs a complement about kidneys in gastronomy. Lamb or veal kidneys are commonly used in Europe and probably other parts of the world, as well as pig; of couse, kidneys are also eaten in poultry or rabbit. I am not an expert myself, maybe refer to the French Wikipedia, there must be something about "rognons" (we do not say "reins" in French when we eat them)

Weight

In a normal human adult, each kidney is about 10 cm long, 5.5 cm in width and about 3 cm thick, weighing 150 grams ^[3]. Kidneys weigh about 0.5% of a person's total body weight.

If they are 0.5% of total body weight, a normal human adult must weigh 30kg, which must be under half the actual normal weight. Richard001 22:11, 7 February 2007 (UTC)

Recheck your math. Half of one percent (0.5%) of normal body weight (70 kg) is 0.35 kg or 350 g. --David Iberri (talk) 00:01, 8 February 2007 (UTC)

Yes, I didn't pay close enough attention to the wording, it makes perfect sense with the plural. All the same I'll reword it just so make it clear. Richard001 02:03, 8 February 2007 (UTC)

What happens if my kidneys fail completely?

What happens if my kidneys fail completely?

Complete and irreversible kidney failure is sometimes called end-stage renal disease, or ESRD. If your kidneys stop working completely, your body fills with extra water and waste products. This condition is called uremia. Your hands or feet may swell. You will feel tired and weak because your body needs clean blood to function properly.

Untreated uremia may lead to seizures or coma and will ultimately result in death. If your kidneys stop working completely, you will need to undergo dialysis or kidney transplantation. --142.167.106.79 (talk) 22:19, 18 February 2009 (UTC)

If your kidneys fail completely, you will have end stage renal disease, and will require hemodialysis, peritoneal dialysis or a renal transplant, which are all forms of renal replacement therapy. Remember to sign in, and if the articles don't answer your question, research and edit them yourself! FelixFelix ^talk 14:02, 11 June 2007 (UTC)

Dialysis

The two major forms of dialysis are hemodialysis and peritoneal dialysis. In hemodialysis, your blood is sent through a filter that removes waste products. The clean blood is returned to your body. Hemodialysis is usually performed at a dialysis center three times per week for 3 to 4 hours. Illustration of a man being treated with hemodialysis. [d]

Hemodialysis

In peritoneal dialysis, a fluid is put into your abdomen. This fluid captures the waste products from your blood. After a few hours, the fluid containing your body’s wastes is drained away. Then, a fresh bag of fluid is dripped into the abdomen. Patients can perform peritoneal dialysis themselves. Patients using continuous ambulatory peritoneal dialysis (CAPD) change fluid four times a day. Another form of peritoneal dialysis, called continuous cycling peritoneal dialysis (CCPD), can be performed at night with a machine that drains and refills the abdomen automatically. Illustration of a person being treated with peritoneal dialysis. [d] Peritoneal dialysis Transplantation Illustration of a transplanted kidney. [d]

Kidney transplantation

A donated kidney may come from an anonymous donor who has recently died or from a living person, usually a relative. The kidney that you receive must be a good match for your body. The more the new kidney is like you, the less likely your immune system is to reject it. Your immune system protects you from disease by attacking anything that is not recognized as a normal part of your body. So your immune system will attack a kidney that appears too “foreign.” You will take special drugs to help trick your immune system so it does not reject the transplanted kidney.

Secretion/reabsorption ("Acid-base balance" section)

Since those words are completely confusing to laymen, and sound like the opposite of what they actually mean in renal function, I took the liberty of adding the necessary words "into the blood" when reabsorption is mentioned. I also changed "secretion" to "excretion into the urine." If "excretion" must be changed back to "secretion," please retain my added "into the urine" each time, so readers will know what it actually means. (Normally, when a reader reads the word "secrete," they believe it to mean secrete into the bloodstream or body; and normally when they read the word "reabsorb," they believe it to mean "remove from the bloodstream or tissues.") Softlavender (talk) 04:22, 11 December 2007 (UTC)

I hadn't considered that, but good point. I won't change it, but the term should be "secreted", not "excreted". I'm not moved enough to change it, but if someone does, I agree that the "secreted into the urine" is a reasonable substitution. --David Iberri (talk) 12:44, 28 February 2008 (UTC)

Too anthropocentric

I think this article is too anthropocentric and too medical focussed:

• Human kidneys are just examples of vertebrate kidneys.
• These operate on the same principles as the nephridia of invertebrates, see e.g. Ruppert, E.E., Fox, R.S., and Barnes, R.D. (2004). "Introduction to Bilateria". Invertebrate Zoology (7 ed.). Brooks / Cole. pp. 196–224. ISBN 0030259827.{{cite book}}: CS1 maint: multiple names: authors list (link). The main difference is that vertebrate kidneys get their input from their own branch of the circulatory system, while invertbrates use a variety of transport methods that do no involve blood vesses. BTW all these systems are wasteful of water compared with Malphigian tubules, evolved convergent by various groups of air-breathing arthropods (the structures and mode of operationare similar, but the embryolical development varies between groups).
• As a previous post ("Kidneys are edible...") pointed out, there are also significant non-zoological aspects.

I suggest WP needs:

• A hierarchy of articles about excretory systems to handle the zoological principles, e.g.
  • Excretion
    • Nephridia
    • Kidney dealing with vertebrate-specific aspects.
      • Human kidney to handle medical aspects.
• Kidney should also deal with non-zoological aspects, e.g. as food. --Philcha (talk) 17:38, 30 March 2009 (UTC)

I completely agree. It's a little inconvenient that 'kidney' is used in quite a loose sense in common parlance - however, I think that your choice to restrict it to vertebrate kidneys, and use nephridia to deal with invertebrate organs performing the same function, is very shrewd. I further agree that human kidney warrants an article of its own to deal with aspects which only relate to humans. Martin (Smith609 – Talk) 17:46, 30 March 2009 (UTC)

Too technical?

Might just be me, but this article seems way too technical (or medical, or something) - I tried reading under "functions" just now, only to see that I was better served by reading the Simple English edition. Isn't this supposed to be a general encyclopedia rather than a medical one? I'd suggest keeping the article "Kidney" in more or less layman's terms, and keep the detailed doctor-speak inside the main articles linked to inside this one - "renal physiology" strikes me as much more logical a place to talk about renal sinuses and interlobal nephrons than "kidney". --80.212.160.146 (talk) 00:43, 7 April 2009 (UTC)

(JUST A COMMENT) Actually I thought it was pretty cool how technical it is. The terminology used to describe the functions made me way more interested in kidneys than I thought I ever would be. Not an example, but my favorite part is "despite their relatively small size they receive 20% of the cardiac output"! So cool, i never knew! :D —Preceding unsigned comment added by 94.197.241.106 (talk) 17:55, 26 May 2009 (UTC)

Article plural

Does anyone else see the bold opening title spelled as kidney's rather than kidneys? I have no idea why it appears this way because there is not an apostrophe in the actual code of the term. All I can figure is there might be some other code in the article affecting it. There should not be an apostrophe (see Wiktionary:kidney#Noun) because that would be for when talking about a single kidney's attributes. Conversely the plural possessive form would be kidneys' or kidneys's. Dictabeard (talk) 19:17, 23 January 2011 (UTC)

Kidney function in excretion -- explanation and diagram of countercurrent mechanism needed

This article, and the ones kidney physiology and nephron very much need a good explanation, with diagrams, of the central role of active transport and countercurrent mechanisms in enabling kidney function. Such an explanation can be found, with diagrams, in http://www.zuniv.net/physiology/book/chapter25.html . Once these principles are explained, kidney function makes sense, including adaptations such as the kangaroo rat's long loop of Henle, which (together with other physiologic and metabolic adaptations) enables it to produce such concentrated urine that never needs to drink, subsisting on water metabolically produced from dry food materials.

While the left kidney has a bold label compared to the others the image should be renamed to "Horizontal cross section through the kidneys". Does this seem like a reasonable name for the image? We will need an administrator to rename the file though can correct the image caption now.

Assuming I interpreted things correctly the person's back is towards the bottom of the image and:

• The white thing between the kidneys is the spine.
• What's the circular thing just below the spine in the image? I assumed the spinal column is within the spine.
• What's the thing that's immediately above the right kidney in the image? I'm guessing it's part of the colon
• At the top of the image is a structure identified as an umbilical vein. It appears this cross section is of either a fetus or less than one week old baby. Are the features shown in this image the same as what would appear in an adult? For example, before I realized the significance of the umbilical vein I was wondering why there seemed to be so little fat. If it's a fetus then the absence of fat would make sense.

Introduction is bad

The introduction seems to contain lots of redundant sentences. Someone should shorten it. E.g. "Their main function is to regulate the balance of electrolytes in the blood, along with maintaining pH homeostasis." and "Kidneys are essential to the urinary system and also serve homeostatic functions such as the regulation of electrolytes (including salts), maintenance of acid–base balance, maintenance of fluid balance, and regulation of blood pressure (via the salt and water balance)." both say that Kidneys are important for electrolytes and pH.77.179.8.100 (talk) 06:26, 28 November 2016 (UTC)

Riddle for kidney article readers

So - is a kidney an organ or a food? And which is correct: a "kidney shaped bean" or a "bean shaped kidney"? Regards IiKkEe (talk) 14:36, 20 September 2017 (UTC)

Format under "Blood supply"

The following discussion is closed. Please do not modify it. Subsequent comments should be made on the appropriate discussion page. No further edits should be made to this discussion.

I am interested to know if the format under Blood supply is acceptable as per WPMOS: the use of footnotes in a table with explanation of the footnotes under the table in bullet format. Can anyone help me with whether that is acceptable? I personally see no problem with it, and if it compatible with WPMOS, I can think of other WP articles where using that format would be useful. If it is not in compliance with WPMOS, I presume the solution is to move the footnote explanations to the bottom of the article minus the bullets. Input would be appreciated. IiKkEe (talk) 13:58, 22 September 2017 (UTC)

I do not feel such a table is ideal. We generally present information in a discursive format as we are WP:NOTTEXTBOOK. I generally find notes attached to tables contain tidbits tangential to the primary topic best located on other articles. --Tom (LT) (talk) 21:50, 22 September 2017 (UTC)

Vertebrate kidneys

What kind of kidneys does this article describes? The basic definition is: "The kidneys are two reddish-brown bean-shaped organs found in vertebrates". But vertebrates can have pronephros, mesonephros and metanephros. Moreover metanephros is different in mammals, reptilians and birds. And only the metanephros of mammals is usually bean-shaped. But not always, as one of horse's kidneys is heart-shaped.

This article is about the human kidneys. But it made so that it looks like it describes vertebrate and mammalian kidneys too. It's a huge original research as I think. Separate article must be created to describe the kidneys of vertebrates, the kidneys of mammals and the human kidneys. -- D6194c-1cc (talk) 16:48, 8 May 2022 (UTC)

• I changed the basic definition and made a separate Wikidata item Q111907436 for the vertebrate kidney. -- D6194c-1cc (talk) 20:16, 8 May 2022 (UTC)
• I tried to rename the article to Human kidney but my actions were reverted. Could somebody rename my sandbox page to Kidney page? User:D6194c-1cc/sandbox/Kidney.

• @Praxidicae: You reverted my edit: [1]. But the sources cannot contain information that vertebrate kidneys are bean-shaped or about their color. Please revert my citation request back. It was absolutely correct. --D6194c-1cc (talk) 20:59, 9 May 2022 (UTC)

  It's literally in the first paragraph of "Structure"[2]. PRAXIDICAE💕 21:00, 9 May 2022 (UTC)

  This source is about human kidney, see upper categories: Health -> Human Body -> Body Systems -> Kidney & Urinary Tract. It can't be used to describe vertebrate kidneys at all. --D6194c-1cc (talk) 11:24, 10 May 2022 (UTC)

The article is certainly very biased towards human kidney's, but that's probably reasonable given the average reader's interests. I suggest that if you have more content to add regarding the kidney in other animals, then Kidney#Other animals has plenty of scope for expansion. Once it's large enough there would certainly be a case for a split. Otherwise, I suggest refining the structure to address the over-generalizations.

It's not biased. It's about human/mammalian kidneys but the first sentence is misleading and says nothing that could be applicable to all vertebrate kidneys. And only the "Other animals" section has some common information about kidneys in other animals. Almost nothing said abut bird kidneys and about reptilian kidneys. Mammalian kidneys are different between species. They vary in lobules count and papilla form (fused or not fused). For example a cow has visually lobulated kidneys. Can we say that they are bean-shaped? What about differences in structure and function of kidneys between animal classes? --D6194c-1cc (talk) 17:30, 20 May 2022 (UTC)

Regarding your category argument, there are many ways of view the 'hierarchy', which is really more of a web; for example, Category:Animal anatomy:Category:Urinary system:Category:Kidney is also a valid current reading of the categories. Klbrain (talk) 09:50, 14 May 2022 (UTC)

It's not about category, it's about wrong information in the definition. The definition creates an illusion that it describes the vertebrate kidney, but it describes the human kidney. And all information in the preamble is about human kidneys, preamble says nothing about other animals or about their kidney types. --D6194c-1cc (talk) 17:34, 20 May 2022 (UTC)

This editor has created Kidney (vertebrates). In my opinion this matches the intended scope of Kidney and I have suggested a merge — Martin (MSGJ · talk) 06:48, 21 May 2022 (UTC)

My new article is about vertebrate kidneys and is specialised on animals (vertebrates) without human context. If you compare the preambles of those two articles you will see all the difference between human and general kidney description. This article must be transformed into the human kidney, because is mostly describes the human kidney with a little bias to the mammalian kidney (since human kidney is mammalian, too). The only section about vertebrate kidneys is Kidney#Other_animals. The whole article is made upside down. --D6194c-1cc (talk) 13:32, 22 May 2022 (UTC)

Kidney structure image in the article

KidneyStructures PioM

The arteries and veins are illustrated as a ladder in the cortex. But as I read before it must be some kind of a tree: the interlobar (between kidney lobes) artery -> arcuate artery (between cortex and medulla) -> interlobular arteries (between cortical lobules) -> afferent arterioles (they supply nephrons). The image made wrong. It would be hard to explain the meaning of the 12 number. --D6194c-1cc (talk) 20:49, 13 June 2022 (UTC)

Kidney → Human kidney – The Kidney article describes human kidneys with little bias to mammalian kidneys. A new article about vertebrate kidneys has been created to describe kidneys carefully without any bias towards human or mammals. Human anatomy must be split from other animals because combined articles are highly biased towards human and create misunderstandings or even give wrong information like bean-shaped kidneys in all vertebrates (fishes are vertebrates too).

@D6194c-1cc: What do you propose should be done with the "main" kidney page? Should kidney (vertebrates) be moved to "kidney"? Should a disambiguation page be created there? Natg 19 (talk) 23:15, 22 June 2022 (UTC)

Main page must be transformed to describe human kidney. In fact, most of the article is just about human kidneys. Human kidney is well described with a lot of good quality sources. But information about human kidney cannot be used to describe vertebrate kidneys. For example mesonephric kidneys of fish are not bean-shaped, their nephrons doesn't have the loop of Henle and even some marine marine fish species have aglomerular nephrons.

Some nephrons of fish have non-integrated nephrons. In amniotes metanephric kidneys are also quite different in structure, form and function. Of course, all kidneys are made of nephrons which filter blood, but kidney tissues and structure can differ. Some facts must be correctly attributes to human or other animal classes. For example if the article says that kidneys help to produce vitamin D, then it must be correctly attributed to human according to the source that was used for this information. To say so about amniotes another reliable source is needed because their kidneys can have no such function. Produced hormones can also vary between classes. If we say about erythropoietin than we must attribute information to appropriate animals accordingly to the used source. Renin function is also different in fish compared to mammals. Also mammals are the only class of animals that doesn't have renal portal system in kidneys.

Separate articles about the human kidneys, mammalian kidneys, vertebrate kidneys and nephron must be made. Separate article about human kidneys is very important because kidney is vital organ in human and is related to medicine too. --D6194c-1cc (talk) 05:03, 23 June 2022 (UTC)

My question is more of what should be done with "Kidney"? Should it be a page with links to "human kidney" and "kidney (vertebrates)"? Natg 19 (talk) 17:04, 23 June 2022 (UTC)

We should probably provide a list of possible names to discuss it. Those are:

• Kidney with about-distinguish template, Kidney (vertebrates)
• Human kidney, Kidney (vertebrates), Kidney as disambiguation page
• Human kidney, Kidney with about-distinguish template

I prefer the Human kidney and Kidney variant because it would be enough to place about-distinguish template to the Kidney article and in some future I'll write an article about mammalian kidneys which would have section about human kidneys with the link to the main page. So those article could form a tree with Kidney -> Mammalian kidney -> Human kidney branch. --D6194c-1cc (talk) 17:38, 23 June 2022 (UTC)

But if a separated article about kidneys as food would be created then Human kidney, Kidney (vertebrates), Kidney as disambiguation page variant would be better. --D6194c-1cc (talk) 21:34, 23 June 2022 (UTC)

• Oppose per WP:ASTONISH and WP:PRIMARYTOPIC. When you think of (a) kidney, most people would assume you mean the human kidney, and the extra dab is not needed. Lugnuts ^{Fire Walk with Me} 07:26, 23 June 2022 (UTC)
• Support in general for these discussions I think the main page has to satisfy two conditions - (1) the primary topic is what readers expect, and (2) there is enough content to justify a split. I think this meets both criteria. The use of kidneys as a food in particular throughout society in addition to the kidney as an anatomical structure means, I think, that readers would not be astonished to see the primary page of this topic being the general structure. Regardless of the outcome I think we should also acknowledge the great contribution by the nominator writing this article. Tom (LT) (talk) 11:00, 23 June 2022 (UTC)

  I agree think that information about kidneys as food should also be moved to a separate article (something like Kidney (food)). It has no relation to the kidneys in biology context. It's just about nutrition and cooking. Moreover, it is very strange to see the section about kidneys as food in an article that is about human kidneys, even if it doesn't says directly that it is about human. --D6194c-1cc (talk) 21:17, 23 June 2022 (UTC)

• Support per Tom. We need to be specific in this instance that this page is about human kidneys. Also, move the vertebrate kidney page to "kidney". — Preceding unsigned comment added by Spekkios (talk • contribs) 00:11, 29 June 2022 (UTC)
• Oppose. Yes, this article really is the kidney article; it is not a "human kidney" article pretending to be a kidney article. The main article should cover the broad range of subtopics. This includes humans and other animals (and yes, history and culture, including food, to some degree), as this article does. The organization of content should follow principles such as Wikipedia:Summary style and Wikipedia:Broad-concept article. (It should not be based on principles of trying to mirror taxonomic hierarchies such as vertebrate > mammal > human. It should also not use Template:about-distinguish as if it were a substitute for a broad-concept article.) What may not be obvious, though, is that appropriately broad coverage will often result in giving more attention in total to subtopics specific to humans (e.g. human medicine), or to human-oriented coverage of subtopics not technically unique to humans. This is not improper bias toward humans, but in fact is as WP:NPOV requires: treating aspects of the subject with weight proportional to the attention given to them in the aggregate body of sources. An approach pervasively taking care to emphasize comparisons between animals and scrupulously avoiding "bias" toward humans is, in the bigger picture, a narrow point of view of the topic. The general organization I've described is also consistent with articles such as Lung or Heart. It is true that other differently-organized articles exist, and at some point there may be such long detail that the way to achieve summary style is to spin off a separate "human kidney" article, but we are not at that point. The current kidney article does not perfectly achieve the principles I've mentioned (and for that matter, certainly doesn't achieve the difficult ideal of making technical articles understandable), but it's the article with the right general idea. For these reasons I oppose the move.

I also would discourage a full merge, since Kidney (vertebrates) goes into detail which is appropriate for itself, but greater detail than the broader-scoped main article should have. This is not a general opposition to editing how this article summarizes animals, and not an opposition to partial transfer of content from one article to the other. (As a small example, I think having the first sentence describe the function of the kidney, as Kidney (vertebrates) currently does, is more helpful than starting with the shape and color.) Lastly, I applaud the nominator's work on Kidney (vertebrates), and I look forward to your continued contributions in this and other areas. Adumbrativus (talk) 13:28, 29 June 2022 (UTC)

• As said below the article has the "Other animals" section which means per the anatomy guidance that this article is about human kidney which pretends to be a kidney article (as we see from the basic definition). The example of an article around human anatomy is Human leg in oppose to Leg as more common article. --D6194c-1cc (talk) 16:09, 1 July 2022 (UTC)

• Oppose, per Lugnuts. Often, per the anatomy guidance, there's an "other animals" section. But Kidney (vertebrates) is its own article right now. GBFEE (talk) 22:24, 30 June 2022 (UTC)
  • WP:MEDTITLE: "The word human is usually omitted in titles, but it may occasionally be helpful if non-human references to the structure are common. For example, compare the articles at Leg (including insect legs, robotic legs, etc.) and Human leg. However, if the article is about humans and the reader will expect to find information about humans under that title, e.g., Arm and Pregnancy, then pre-disambiguation of the title is inappropriate." Links to the Kidney page: Special:WhatLinksHere/Kidney. Many of them are from articles on non-human or common topics. — Preceding unsigned comment added by D6194c-1cc (talk • contribs) 15:59, 1 July 2022 (UTC)
    • D6194c-1cc, do you mind explaining what you mean by quoting WP:MEDTITLE? The kidney article is about humans and the reader will expect to find information about humans under this title. That's what Lugnuts is arguing. And Adumbrativus highlights this as well, by saying, for example, "What may not be obvious, though, is that appropriately broad coverage will often result in giving more attention in total to subtopics specific to humans (e.g. human medicine), or to human-oriented coverage of subtopics not technically unique to humans. This is not improper bias toward humans, but in fact is as WP:NPOV requires: treating aspects of the subject with weight proportional to the attention given to them in the aggregate body of sources." So my oppose is also "per Adumbrativus" to a degree. I didn't notice before, but I've noticed now that there is an "other animals" section in the article. The existence of that section doesn't mean that the kidney article is not an article that is about humans. Per the anatomy guidance, it's common for articles that are predominantly about humans to have such sections. If there's a dedicated article for other animals and an "other animals" section in the article, then we link to that in that section as "main article" for more information. GBFEE (talk) 21:16, 1 July 2022 (UTC)
      • As per WP:MEDTITLE some articles about animals or general anatomy articles refer to the Kidney page and those articles do not expect that the reader will go to the human kidney page. In my previous reply I provided the link to a list of articles that refer to the Kidney page (Special:WhatLinksHere/Kidney). They include Organ (biology), Amphibian, Reptile, Dinosaur, Bird, Common ostrich, Rat, Camel, etc. --D6194c-1cc (talk) 07:55, 2 July 2022 (UTC)
• Oppose although I understand the reasoning. From a physiology point of view, what is currently at Kidney (vertebrates) is "the kidney article" and this here is an in-depth treatment of a subtopic. However we do have a site-wide habit (spottily observed) of having such search terms land on the human physiology version rather than the generic one, so I don't think there's a call to break from that in this instance. I think the current setup, with a nice long summary of Kidney (vertebrates) and a {{Main}} link there works well. -Elmidae (talk · contribs) 13:22, 4 July 2022 (UTC)

Two links to renal?

The lead to this article has two links to the word renal, which is itself a redirect to this page. That seems unnecessary, and I can't think of why it would need to be linked at all, unless it's meant to be the Wiktionary link for etymology. I'm hesitant to remove it in case there was some specific reason, though. Thoughts? - Procyonidae (talk) 10:18, 24 July 2022 (UTC)
