Expert Answer:

Villi are folds of intestinal skin, hence they will greatly increase the surface area compared to a plain surface without folds. Villi are for absorption, hence they will greatly increase the absorption from the intestine to different parts of the body. Villi are richly supplied with blood capillaries.
