Moved to talk
I moved the following text from the main article which contain details which seem to belong in the urine and or feces pages: "While from jelly fish urine and feces are both waste material of body processes, they are in completely different categories. Urine is a waste product of the urinary system process while feces are waste products of the digestive system. Feces may contain about one-third bacteria, most of which are harmless, even beneficial while in the gut, but dangerous to others and they may also contain virulent and even deadly pathogens in the form of bacteria, viruses, amoebae, and various parasitic worms. Urine, on the other hand, megue contains excess water, salt, and protein waste in the form of urea as uric acid, and seldom any pathogens; should a person be in a situation of insufficient water and in danger of overheating due to lack of perspiration, urine may be safely used to dampen clothing to aid cooling. It is futile to attempt to drink it (or salty ocean water), as it requires more water from the body to excrete the salt than is available in the fluid. Some sea birds are able to efficiently excrete excess salt through the tear ducts associated with the eyes. Such birds can drink sea water without harm." — Preceding unsigned comment added by Johndarrington (talk • contribs) 08:19, August 7, 2005 (UTC)

recent change
Link added for elimination links to disambiguation page, but I still think it provides a usefull and interesting additional path of information. Possibly more correct to link it to clearance or defecation (which is already in the "see also").

There is a grammatical error in the first sentence. Please fix. —Preceding unsigned comment added by 98.14.113.232 (talk) 21:34, 18 April 2010 (UTC)

Stop Vandalizing This Article

 * You're only feeding the trolls who vandalize by saying you find it disturbing. Articles like this get vandalized all the time. There are several useful things you can do about it however. You can start by reverting it on sight. Make sure you get all of it, don't just revert to an unclean version. Also be sure never to do it manually, as you may end up deleting a section that was fine before the vandal messed around with it. If people do a lousy job of reverting themselves, let them know about it (politely). Secondly, don't just add a misleading template. If you want it protection, go to Requests for protection and ask. If you want political change with the Wikipedia system, campaign to require a login to edit (almost all vandalism comes from IPs, but then they also contribute good stuff as well, so it's a tricky issue. You are presumably an anon yourself, so you can see my point).
 * If there's anything I can be certain about it's that this article will be vandalized again. Don't complain about it, just revert it. And please sign your posts. Richard001 07:23, 15 August 2007 (UTC)

I agree. You WILL just make them want to vandalise more as a reaction is what they want from you. —Preceding unsigned comment added by 88.106.212.165 (talk • contribs) 14:03, 22 February 2009

Maybe add a section on excretion in eggs?--68.193.135.139 (talk) 02:00, 31 May 2010 (UTC) —Preceding unsigned comment added by 69.57.241.252 (talk) 23:41, 8 June 2010 (UTC)

Pic caption
"Insects, birds and some other reptiles also undergo a similar mechanism."

1. Does that mean they excrete faeces + uric acid? Not clear. 2. "undergo... a mechanism" is odd English. And an insect, bird, reptile, gerbil or human can't be said to _undergo_ a mechanism. Notreallydavid (talk) 05:33, 22 July 2010 (UTC)

Proper usage of the word
Merriam-Webster's online medical dictionary provides two definitions of "excretion" ; the first refers to the elimination of metabolic waste as discussed in this article, and the second refers to feces but is "not used technically." The non-Wikipedia sources in http://answers.com/excretion state that "excretion" refers to "both urination and defecation" or, generally, to the "transfer of substances out of a living organism into its environment." — Preceding unsigned comment added by 68.55.112.31 (talk • contribs) 00:29, 2 May 2012

Excretion options
How about things like bile, saliva, and breast milk excretion? 129.180.166.53 (talk) 14:43, 9 June 2012 (UTC)

Excretion alteration depending on urine
Weak acids more easily secreted in alkaline (basic) urine. Weak basis more easily secreted in acidic urine. 129.180.166.53 (talk) 14:46, 9 June 2012 (UTC)
