Edit request 14mar2023, uric acid versus ureum: This version claims "In humans and other amniotes (mammals, birds and reptiles) most of these substances leave the body as urine and to some degree exhalation, mammals also expel them through sweating." I believe this sentence is wrong. It should read "fish and amphibians", instead of "Birds and reptiles". Birds and reptiles excrete in the from of "uric acid" which is not watersoluable. As such, birds and eptiles do not 'pee'. The article itself mentiones this under biliary system as it mentions of "fish and amphibians", as well as "Uric acid is paste-like and expelled as a semi-solid waste (the "white" in bird excrements)." Due to this often overlooked difference, lifestock waste management of poultry (birds) is quite different from waste from mammals or fish. Someone else may elaborate on that difference at an appropriate place.

I believe this improves the article in a whole. — Preceding unsigned comment added by 2A02:A46F:9B7:1:8552:A836:6616:7DDA (talk) 14:03, 14 March 2023 (UTC)
