Question

How do villi increase the surface area?​

Answer 1

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.
