Defecation

Defecation is the final act of digestion, the elimination of solid, semisolid, or liquid waste material (feces) from the digestive tract via the anus. It's a complex physiological process involving the coordinated action of the digestive system, the nervous system, and the muscular system. The process is triggered by the filling of the rectum, which stimulates stretch receptors, initiating the urge to defecate. Efficient defecation requires proper bowel motility, adequate hydration, and a healthy diet. In humans and other mammals, the process serves to remove undigested food residues, bacteria, dead cells, and other waste products from the body, maintaining internal homeostasis. Disruption to this process, such as constipation or diarrhea, can signal underlying medical conditions.
