Final answer:
The anus is the muscular opening through which wastes are removed from the body. The rectum stores feces until defecation. Two sphincters regulate the elimination of feces through the anus.
Step-by-step explanation:
The anus is the muscular opening through which wastes are removed from the body. It is located at the far-end of the digestive tract and acts as the exit point for waste material. The rectum, which is the terminal end of the large intestine, stores feces until defecation. Two sphincters, the inner sphincter (involuntary) and the outer sphincter (voluntary), regulate the elimination of feces through the anus.
