ANATOMY

Detailed explanation-1: -The rectum is where feces are stored until they leave the digestive system through the anus as a bowel movement.

Detailed explanation-2: -Partly digested food moves through the cecum into the colon, where water and some nutrients and electrolytes are removed. The remaining material, solid waste called stool, moves through the colon, is stored in the rectum, and leaves the body through the anal canal and anus.

Detailed explanation-3: -The rectum receives stool from the colon, sends signals to the brain if there is stool to be evacuated, and holds stool until evacuation can happen. Anus: The last part of the digestive tract, the anus, consists of pelvic floor muscles and two anal sphincters (internal and external).

Detailed explanation-4: -The colon’s job is to dehydrate what’s left of the food and form it into stool. It does this by slowly absorbing water and electrolytes as its muscle system moves the waste along.

Detailed explanation-5: -The colon includes the ascending colon, cecum, transverse colon, descending colon, sigmoid colon, and rectum.
