Detailed explanation-1: -Bacteria in the colon help to digest the remaining food products. The rectum is where feces are stored until they leave the digestive system through the anus as a bowel movement.
Detailed explanation-2: -The body expels waste products from digestion through the rectum and anus. This process, called defecation, involves contraction of rectal muscles, relaxation of the internal anal sphincter, and an initial contraction of the skeletal muscle of the external anal sphincter.
