small intestine

the small intestine is a winding, tightly folded tube about 6 m (20 ft) long in adults. it is connected to the stomach on the top end and to the large intestine (colon) on the bottom end.

most of the food a person consumes is digested and absorbed in the small intestine. the lining of the small intestine has tiny finger-shaped raised tissues (villi). these raised tissues greatly increase the surface area of the intestine, which absorbs calories and nutrients from food.
