Feces always passes through the excretory system![edit]

Anyone who has taken high school biology should know that feces is a product of the digestive system, not the excretory system. Someone please fix this article for accuracy. —The preceding unsigned comment was added by (talk) 07:21, 16 January 2007 (UTC).

Im deleting faeces from the list as suggested above. This is an example of egestion, not excretion.Odmrob 19:18, 28 January 2007 (UTC) Yea i am awesome ilovefriedchicken1228576 — Preceding unsigned comment added by (talk) 17:24, 13 February 2012 (UTC)

Yeah But The Kidney Isn't Part Of The Excretory System So I Could Argue Both Sides[edit]

I am learning that the urinary system is not only closely related, but a huge part of the excretory system!

'Excretory system' is a functional definition not nomenclature Markjohndaley 14:49, 7 May 2007 (UTC)

Proposed Merge[edit]

In various sources such as Encyclopedia Britannica, the excretory and urinary systems are indeed the same system. If a merge follows, the name should be changed to Excretory system as this is the proper name. --I Are Scientists 19:31, 9 April 2007 (UTC)

The former name of the poopinary system is excretory, i agree but changing the name of excretory to poopinary system made it distinct from the rest of our body system that also excretes waste like the integumentary system and digestive system, sometimes, calling the urinary system made our students confused as with the function of the urinary system, they are inquiring that elimination of waste is a sole funtion of this system. =ton2n17=

This article should not be moved into the excretory system. Many of the major body systems

As I have posted in the Urinary system I absolutely dispute the merge. This topic is a medical one and, for instance, the 33rd edition of Gray's Anatomy calls it the Urogenital system (which would be a better name if a change was warranted). Bern and Levy, Physiology 5th edition, refers to get sme ass e urinary tract (pg 630). Excretory system is an ambiguous term.

Aping Brittanica is not what writing Wiki articles is about. It is about proper research and referencing. As the Various sources you have mentioned only that one. Don't make me quote every single medical text I have! Markjohndaley 14:45, 7 May 2007 (UTC)

This article should stay seperate but have a link in the system to put them together. But each system is connected.User:NAVYCHAPPY 16:02, 22 September 2007 (UTC)

I say no merger, the urinary system is a major organ system and has little to do with feces from the digestive track. These are two separate topics and the articles should remain separate. Earthdirt (talk) 19:34, 27 November 2007 (UTC)

Same and Different[edit]

It;s really confusing because there are ONLY 11 Systems.....but we should learn that the Urinary system should have it's own article in Wikipedia ////// Ayyah tubby (talk) 14:24, 7 December 2007 (UTC)

Dudes the excretory system is the urinary system. Also feces is part of the digestive system. This page is inaccurate!!! —Preceding unsigned comment added by Drei242 (talkcontribs) 16:09, 23 February 2008 (UTC)

Don't worry girls and boys[edit]

Drei242 is on the job i have already taken out most f the unneeded areas and the false areas. I understand that feces, bile, and the large intestine have nothing to do with the excretory system so ill delete these parts. Finally we can fix this page. I wonder who made this inaccurate page?

Merge? Not?[edit]

I don't know... but since the urinary system is part of the excretory system, it could be under 'excretory system'... could. I disagree. It shouldn't be merged. Miley1006 (talk) 01:49, 24 February 2008 (UTC) Just delete this article. It stinks and it inaccurate. —Preceding unsigned comment added by (talk) 02:18, 3 April 2009 (UTC)

The Excretory System[edit]

Without the excretory system we would all be dead beacause the excretory system cleans your blood,and sends the wastes from your blood out with your urine. The execretory system is also known as the Urinany system. It is one of the eleven major body systems in animals. —Preceding unsigned comment added by (talk) 01:26, 28 October 2008 (UTC)

Why separate liquid and solid waste systems?[edit]

Mention what's the "design decision" with separate disposal systems: urination vs. bowel. Any animals have them combined into one system? Jidanni (talk) 23:26, 29 May 2009 (UTC)

Copyedit, cleanup and reformatting[edit]

Fixed a lot of the grammatical errors, moved the intro to better spots and took out some of the extraneous information (the long explanation of kidney function probably is more suited to the Kidney page). Still need citations though!

Incidentally, I adopted the position that the excretory system isn't actually distinct from other systems (kidneys and liver process blood => circulatory, rectum takes undigested food => digestive), so I'm just avoiding the issue entirely. stop debating over this cause its not helping —Preceding unsigned comment added by (talk) 10:37, 27 July 2010 (UTC)

Cannot be merged[edit]

I believe that the articles "Excretory System" and Urinary System" cannot be merged because Urinary may be a part of the excretory but Urinary is only for liquid excretion rather than solid and gas; however it may also be merged, but the excreory being divided into two parts: The urinary and.. a system we may call for the solid excretion or egestion as you may say, Like Egestory System? But digestion is mainly different from excretion; because the diegstive system digests and distributes food to our body, sending wastes to the excretory system. Hmm.. this article is kinda confusing.. but goodluck to the editors! :) Coleet (talk) 14:34, 18 October 2010 (UTC)


I can't understand the logic that's behind the order of sections in this article. Kidney, then defecation, then ureter...I think it would be better to make one section for urinary system and leave the others as they are. Furthermore, I think that the paragraph about urine formation is really too poor, giving very simplified (and not too correct) informations: I don't know if it's appropriate in this article. --Doc.mari (talk) 15:38, 4 December 2010 (UTC)

Elaboration/more useful info[edit]

e.g. 1. "For example, as your cells break down amino acids, they produce a dangerous toxin known as ammonia" Is better written as : "For example, as amino acids are metabolized, or stored, the amino group is often removed in a process called deamination, which produces ammonia as a product. Ammonia is a highly toxic compound which must be removed, as its accumulation within blood and tissues is damaging.

2. "Skin is an excretory organ. Although regulation of body temperature causes it to produce sweat which contain urea and other waste with salts too but the secretion of any type of waste for any purpose from the body is called excretion even if it is surplus water."

"Skin is an excretory organ. Although regulation of body temperature causes it to produce sweat which contain urea and other waste with salts too but the secretion of any type of waste for any purpose from the body is called excretion even if it is surplus water.About 5-10% of metabolic waste is excreted through the skin"

3. A function of the kidney worth noting also is regulation of blood pressure. A lot of blood pressure medication target the kidneys (angiotensin/ACE inhibitors etc. )

4. It should be noted that ultrasound treatments ( lithotripsy ) can cause mother kidney stones to fragment into smaller, and sharper stones which may lead to bleeding/kidney damage.

5. "After the filtration process, the blood then returns to collect the food nutrients it needs, while the wastes pass into the collecting duct, to the renal pelvis, and to the ureter, and are then secreted out of the body via the urinary bladder."

"After the filtration process, the blood then returns to collect the food nutrients it needs through the peritubular capillaries, to the renal pelvis, and to the ureter, and are then secreted out of the body via the urinary bladder." — Preceding unsigned comment added by Endless Bigonema (talkcontribs) 19:50, 2 December 2012 (UTC)

guyz can i have some answers?[edit]

guys can i have some answers of my questions? — Preceding unsigned comment added by (talk) 20:09, 23 May 2013 (UTC)


who control the excretory system of humans? (a) brain (b) spinal cord? — Preceding unsigned comment added by (talk) 18:02, 8 September 2014 (UTC)


This page has minimal information about the disorders of the Excretory system. This should either be added or a link to a list of this body system's disorders and diseases should be provided. Yea55 (talk) 17:43, 15 September 2014 (UTC)

Entirely human centred[edit]

Other animals have excretory systems too, some quite different from those of mammals. This article is the logical place to link a whole heap of zoology articles where the excretory system is mentioned in passim. Should all non-mammal considerations go at the end, or be spread out in the article? Petter Bøckman (talk) 23:25, 24 December 2014 (UTC)

Unlock please[edit]

Or fix basic spelling mistakes..

Peer Review-Eccrine Glands, Pyelonephritis (and 3 classifications), and Kidney Stone Sections[edit]

I like how well you explained what the eccrine glands are. Your wording is neutral and easy to understand. I think it would be beneficial to include more information on how the water is perspired out of these glands. In addition, explaining why body temperature needs to be regulated could provide clarity in terms of the need for the eccrine glands in the human body.

Your explanation of pyelonephritis is very simple. I like how you split this infection into three main types of classifications and described the symptoms for each classification. This makes it very easy to understand. I think it would help to include the treatments for all three sections instead of just for acute pyelonephritis. I also think it may be a good idea to include some statistics of how prevalent pyelonephritis is or if certain populations are at higher risk for developing the infection.

This section clearly defines the process and physical attributes of kidney stones. I was able to develop a sound understanding as to how they develop and what they look like. All information in this section was relevant towards the topic. Towards the end extreme cases are mentioned where great pain, bleeding, and blockage of urine can occur. I would add how these cases would be dealt with in opposition with the normal cases where the stones are normally passed. Since previously in the article it is mentioned how they usually pass I would describe what happens if the patient is unable to pass them on their own. Berman madison (talk) 17:51, 10 April 2017 (UTC)
