The elimination of fecal waste through the rectum and anus.

Defecation or feceation is the act or process by which organisms eliminate solid or semisolid waste material from the digestive tract.

Humans remove waste anywhere from several times daily to a few times weekly. Waves of muscular contractions known as peristalsis in the walls of the colon move fecal matter through the digestive tract towards the rectum for elimination.

Waste or excrement from the digestive tract which is formed in the intestines and expelled through the rectum.

Feces consist of water, food residue, bacteria, and secretions of the intestines and liver.

Gross examination of feces for color, odor, quantity, and consistency plus microscopic examination for the presence of blood, fat, mucus, or parasites are common diagnostic procedures in medicine.
