The digested food is taken up by the walls of the intestine. The inner lining of the small intestine has numerous finger-like projections called villi which increase the surface area for absorption. These villi ensure maximum absorption from the digested food.

The villi are richly supplied with blood vessels which carry the absorbed food to different parts of the body. The unabsorbed food from small intestine is sent into the large intestine where more villi absorb water from this material.
