Answer:
Ans:-The main function of the small intestine is to absorb the nutrients obtained as a result of digestion. The lining of the small intestine has finger-like projections called villi that increase the surface area of the lining. This makes absorption more efficient. Each villus has a network of fine blood vessels. Nutrients are absorbed into the blood present in these fine blood vessels.
