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.
Size. The small intestine is only about as big around as a middle finger, according to the MUSC Digestive Disease Center. The large intestine is much wider than the small intestine, but it is also much shorter. The small intestine is the longest part of the digestive system. According to the Cleveland Clinic, the small intestine is 22 feet (6.7 meters) long, while the large intestine is only 6 feet (1.8 m) long.
