62. Picture of Intestines
The small and large intestines are vital organs for digestion. The small intestine connects the stomach to the large intestine. It is composed of three sections: the duodenum, jejunum, and ileum. After the stomach breaks down the contents of food, it passes into the small intestine where nutrients are absorbed. Waste material passes into the large intestine, which is also called the colon. The large intestine absorbs water from the waste material and forms stool. The latter part of the large intestine is the rectum. As stool forms, nerves in the rectum signal the need to defecate. Stool leaves the body via the opening to the outside, the anus.
