It extends from the stomach ( pylorus) to the large intestine ( cecum) and consists of three parts: duodenum, jejunum and ileum. The main functions of the small intestine are to complete digestion of food and to absorb nutrients. Anatomy (Macroscopy) The small intestine is a specialized tubular structure within the abdominal cavity in continuity with the stomach proximally and the colon distally. The small bowel is about 6 m in the adult. Three subdivisions; "the duodenum, jejunum, and ileum"are defined and characterized by various anatomic relationships. The small intestine is an organ located in the gastrointestinal tract, between the stomach and the large intestine. It is on average 23ft long and is comprised of three structural parts; the duodenum, jejenum and ileum. Functionally, the small intestine is chiefly involved in the digestion and absorption of nutrients. It receives pancreatic secretions and bile through the hepatopancreatic duct. Structure The coiled tube of the small intestine is subdivided into three regions. From proximal (at the stomach) to distal, these are the duodenum, jejunum, and ileum ( Figure 23.18 ). The shortest region is the 25.4-cm (10-in) duodenum, which begins at the pyloric sphincter.
