Velvety tissue lines the small intestine, which is divided into the duodenum, jejunum, and ileum. The large intestine (colon or large bowel) is about 5 feet long and about 3 inches in diameter. The colon absorbs water from wastes, creating stool. As stool enters the rectum, nerves there create the urge to defecate.
In humans, the small intestine is about 20 feet long, and the large intestine is about 5 feet long. Both are situated in the abdomen and form a continuous tube from the stomach to the anus.
