Defecated

Defecation is the process of eliminating feces from the digestive tract through the anus. Defecated is the past tense form used to describe a completed act of this process. In humans and many animals, defecation is a normal, essential function that aids waste removal and helps manage fluid balance.

Feces are formed in the large intestine as water is absorbed; material travels to the rectum where it is stored until defecation. The act is governed by reflexes and voluntary control. The internal anal sphincter relaxes in response to rectal stretching, and the external anal sphincter can be consciously controlled to initiate or delay defecation. Abdominal pressure and pelvic floor muscles contribute to the expulsion of stool.

Normal patterns vary widely. A typical range for adults is from several times a day to a few times a week; stool consistency can range from hard to soft. The Bristol Stool Chart classifies types from hard lumps to smooth, soft stools. Constipation refers to infrequent or difficult defecation, while diarrhea refers to loose or urgent stools. Fecal incontinence is the inability to control defecation. Persistent changes or severe symptoms warrant medical evaluation.

Stool contains water, undigested fiber, bacteria, and waste products. Diet, hydration, gut motility, illnesses, and medications can affect defecation. Good hygiene and proper cleaning after defecation reduce infection risk. Defecation is a common, species-wide biological function and a key indicator of digestive health.
