How the colon pushes waste through the body
The large bowel is made up of the colon and the rectum. Also called the large intestine, the large bowel is the last part of your digestive system. Waste passes from the small intestine into the colon. The colon absorbs the water from the waste, then the semi-solid waste (called stool, feces or poop) travels into the rectum. The rectum stores the stool until you have a bowel movement. Then, the stool leaves your body through the anus.
