The small intestine (or small bowel) is the part of the gastrointestinal tract following the stomach and followed by the large intestine and is where much of the digestion and absorption of food takes place. The small intestine is composed of a duodenum jejunum and ileum. It receives bile juice and pancreatic juice through the hepatopancreatic duct controlled by the sphincter of Oddi.
