The small intestine and the large intestine are long, tube-shaped organs in the abdomen (area between the chest and the hips). The small intestine is about 20 feet long and includes the duodenum, jejunum, and ileum. The small intestine is where most digestion (the breaking down of food) and absorbtion of nutrients occurs. When the process of digestion is complete, the small intestine empties the residue into the large intestine. The large intestine starts at the end of the small intestine and ends at the rectum and anus. The large intestine is about 5 feet long and its main function is to store unabsorbed food waste and absorb water and other body fluids before the waste is eliminated as stool. The large intestine includes the cecum, colon, rectum, and anal canal. Also called colon or large bowel.
