Anatomical Information about Intestines

What are the bowel, large intestine, colon, rectum, and anus?

The bowel consists of the small and large intestines. The large intestine, which includes the colon and rectum, is the last part of the gastrointestinal (GI) tract. The large intestine’s main job is to absorb water and hold stool. The rectum connects the colon to the anus. Stool passes out of the body through the anus. At birth, the large intestine is about 2 feet long. An adult’s large intestine is about 5 feet long.
