It is located below the stomach and is coiled in appearance. This tube is abour 7.5 m long. It has three main divisons : duodenum, jejunum and ileum. Duodenum is the first part having two different ducts namely bile duct and pancreatic duct. In this tube digested food (partially) is mixed with pancreatic juice, bile juice anf other juices. Jejunum is the middle pary, found only in man. Ileum is the last part of Small intestine.
Total absorbtion takes place in the ileum. This ileum has villi on its surface. This villi increases surface area for absorbtion. The villi have blood vessels, digested food passes villi passes to there and enters the blood stream. Which then transfers to liver and then to the heart.
