How is the Small Intestine designed to absorb Digested Food ?

The small intestine is the site of the complete digestion of food into different components. 
It is the main region for the absorption of digested food.

The inner lining of the small intestine is covered by millions of tiny finger-like projections called Villi.

The presence of villi gives the inner walls of the small intestine a very large surface area for the absorption of digested food.

The villi enormously increases the inner surface area of the intestines (nearly 8 times that of the outer body surface) which facilitates the absorption of digested food. Between the villi are small holes through which the intestinal juice secreted by its glandular cells is poured into the lumen of the intestine.
