The absorption of the digested food takes place entirely in the small intestine through two channels, the capillary blood vessels and the lymphatics of the villi. A villus looks like a small, finger that lies above the intestinal wall surface. Villi are found in a large number in the beginning of the small intestine. But towards the end of the tract, they reduce in number. The lacteals in the villi absorb the fats, while all the other nutrients directly pass into the capillary blood vessels of the villi.
