Defecation (or defaecation) follows digestion, and is a necessary process by which organisms eliminate a solid, semisolid, or liquid waste material known as feces from the digestive tract via the anus.

Colonic crypts (intestinal glands) within four tissue sections. The cells have been stained to show a brown-orange color if the cells produce the mitochondrial protein cytochrome c oxidase subunit I (CCOI), and the nuclei of the cells (located at the outer edges of the cells lining the walls of the crypts) are stained blue-gray with haematoxylin. Panels A, B were cut across the long axes of the crypts and panels C, D were cut parallel to the long axes of the crypts. In panel A the bar shows 100 µm and allows an estimate of the frequency of crypts in the colonic epithelium. Panel B includes three crypts in cross-section, each with one segment deficient for CCOI expression and at least one crypt, on the right side, undergoing fission into two crypts. Panel C shows, on the left side, a crypt fissioning into two crypts. Panel D shows typical small clusters of two and three CCOI deficient crypts (the bar shows 50 µm). The images were made from original photomicrographs, but panels A, B and D were also included in an article and illustrations were published with Creative Commons Attribution-Noncommercial License allowing re-use.

Anus

Opening at the opposite end of an animal's digestive tract from the mouth.

Its function is to control the expulsion of feces, the residual semi-solid waste that remains after food digestion, which, depending on the type of animal, includes: matter which the animal cannot digest, such as bones; food material after the nutrients have been extracted, for example cellulose or lignin; ingested matter which would be toxic if it remained in the digestive tract; and dead or excess gut bacteria and other endosymbionts.

Female placental mammals have completely separate orifices for defecation, urination, and reproduction; males have one opening for defecation and another for both urination and reproduction, although the channels flowing to that orifice are almost completely separate.

From a series of woodcuts (1545) usually referred to as the Papstspotbilder or Papstspottbilder in German or Depictions of the Papacy in English, by Lucas Cranach, commissioned by Martin Luther. Title: Kissing the Pope's Feet. German peasants respond to a papal bull of Pope Paul III. Caption reads: "Don't frighten us Pope, with your ban, and don't be such a furious man. Otherwise we shall turn around and show you our rears."

Toilet humour, or potty or scatological humour (compare scatology), is a type of off-colour humour dealing with defecation, constipation, urination and flatulence, and to a lesser extent vomiting and other bodily functions.

One of the landmark areas is a "Poo Mountain" and some of its missions involve getting cows to drink a laxative prune juice to produce "pooballs" and another fighting The Great Mighty Poo, a giant opera-singing pile of feces as a boss.
