Defecation â Involuntary and Voluntary Bowel Movement Control What is defecation? Defecation is the process of passing out stool (feces) through the anus. This eliminates waste material from the rectum and colon. The process of defecation should be painless, regular and to a certain degree, it is under voluntary control. The rectum usually does not contain feces so as not to trigger local reflexes that can initiate defecation.

Excretion Excretion is the process by which metabolic wastes and other non-useful materials are eliminated from an organism. In vertebrates this is primarily carried out by the lungs, kidneys and skin. This is in contrast with secretion, where the substance may have specific tasks after leaving the cell. Excretion is an essential process in all forms of life. For example, in mammals urine is expelled through the urethra, which is part of the excretory system. In single-celled organisms, waste products are discharged directly through the surface of the cell.

- As feces travels through the large intestine and moves into the rectum, the wall is stretched and pressure within the rectum increases. This creates an urge to defecate. Defecation is the elimination of feces from the digestive tract.
