The small intestine has three distinct regions--the duodenum, jejunum, and ileum . The duodenum is the shortest part of the small intestine and is where preparation for absorption begins . It also receives bile and pancreatic juice through the pancreatic duct, controlled by the sphincter of Oddi . The primary function of the small intestine is the absorption of nutrients and minerals from food, using small finger - like protrusions called villi . </P> <P> The length of the small intestine can vary greatly, from as short as 2.75 m (9.0 ft) to as long as 10.49 m (34.4 ft). The average length in a living person is 3m - 5m . The length depends both on how tall the person is and how the length is measured . Taller people generally have a longer small intestine and measurements are generally longer after death and when the bowel is empty . </P>
