Human Anatomy Â» Digestive System Â» Small Intestine. Small intestine is the longest part of alimentary canal. It extends from the pylorus of the stomach to the junction between cecum and ileum. Much of digestion and absorption of food takes place in the small intestine. The small intestine is divided into three parts: Duodenum, Jejunum and Ileum.
The ileum is the longest part of the small intestine, measuring about 1.8 meters (6 feet) in length. It is thicker, more vascular, and has more developed mucosal folds than the jejunum. The ileum joins the cecum, the first portion of the large intestine, at the ileocecal sphincter (or valve). The jejunum and ileum are tethered to the posterior abdominal wall by the mesentery. The large intestine frames these three parts of the small intestine.
