What is the process of removal of fecal matter from the body?

The removal of fecal matter from the body occurs through a process called defecation. This process begins in the large intestine, where water is reabsorbed and feces are formed. Once the feces accumulate in the rectum, stretch receptors signal the brain to initiate the urge to defecate. The anal sphincters then relax, allowing the feces to be expelled from the body through the anus.
