.
Small intestine is designed to more and more area for absorption of digested food and transfer into the blood for circulation throughout the body. The inner lining of small intestine has a large number of finger-like projections called villi. These villi provide a large surface area for absorption of food. These villi are richly supplied with blood vessels which take the absorbed food to each and every cell of the body, where it is used for obtaining energy, building up new tissues and repairing of old tissues.

Explanation:
The small intestine is the most important part of the alimentary canal for digestion and absorption of food.
It has three regions a U-shaped duodenum, a long coiled middle portion jejunum and highly coiled ileum.
The innermost layer lining the lumen of the alimentary canal is the mucosa. This layer forms irregular folds (rugae) in the stomach and small finger-like foldings called villi in the small intestine.
These modifications increase the surface area for more absorption. Villi are supplied with a network of capillaries and a large lymph vessel called the lacteal.
It transports lipid molecules. The wall of the intestine is surrounded by the blood vessels which assimilates the food molecules to the different parts of the body.
