Feces (also spelled faeces in British English, or fæces) are semi-solid waste products from an animal digestive tract expelled through the anus (or cloaca) during defecation. In humans, defecation may occur (depending on the individual and the circumstances) from once every two or three days to three times a day. Prolonged interruption in the usual routine is called constipation.
The distinctive odor of feces is due to bacterial action. Bacteria produce compounds such as indole, skatole, and mercaptans, which are rich in sulfur, as well as the inorganic gas hydrogen sulfide. These are the same compounds that are responsible for the odor of flatulence.
The word faeces is the plural of the Latin word faex meaning "dregs".
Feces are also known as scat and scatology is the study of feces. Excrement is also another word for feces.
Feces are generally a taboo subject (see toilet humour). This is probably because of the need to keep feces well away from food, for health reasons. The word shit is a vulgar term for feces in English.
Coprophilia, also known as fecophilia, is a sexual attraction to feces. Coprophagia is the extremely hazardous practice of eating feces.
Coprophobia, also known as fecophobia, is a strong irrational fear of feces.
Meconium (also spelled merconium) is a newborn baby's first feces, and is normally passed post-partum. There is a danger that aspiration (inhalation) of meconium can occur if it is passed during labor and delivery. Inhaled meconium can cause a partial or complete blockage of the newborn's airways, and the severity depends on the amount of meconium the baby aspirates. Meconium aspiration affects around 20 percent of all newborn babies worldwide.
Fossilized feces are known as coprolites, and form an important class of objects studied in the field of paleontology.
The faeces of animals is often used as fertilizer: see manure.
HOW TO EAT YOUR POO
It's quite easy, go to the toilet, grab your favourite mag, sit down, strain last night's turkey, get a net, fish it out and dep fry it! (try not to break the shell!)
