intestine or bowel

The intestine, or bowel, with a length about 6.2 meters (22 feet), is the longest portion of the gastrointestinal tract. It lies between the stomach and anus and consists of the small intestine and the large intestine. The intestine is coiled, and the internal surface area is greatly increased by the presence of folds and projections (villi) to enable efficient digestion and absorption. In the small intestine, which consists of the duodenum, jejunum, and ileum, food mixes with digestive juices, and nutrients and water are absorbed into the blood. In the large intestine, which is divided into the cecum, colon, and rectum, feces are formed before passing out of the anus.
