Answer:
Finger-like protrusions on the surface of the intestinal lining called villi make this massive surface area possible. Because the proteins, carbohydrates, lipids as well as many vitamins and minerals are absorbed through the small intestine, nutrient uptake would be greatly inhibited without villi.

Answer:
The small intestine is folded into villi which has many microvilli. The villi has a finger like structure and the microvilli acts as a hairlike on those fingers. Both of them expand to increase the surface area so more nutrients can be absorbed. They both are made up of a single layer of cells.
