The intestinal wall is covered with microscopic protrusions called villi and microvilli. These villi look like millions of tiny fingers or hairs sticking out from the intestinal wall. The villi increase the surface area of the wall because there is now much more membrane per square inch of intestine.

What is the difference between a villi and microvilli?
Both are found inside the small intestine, are microscopic, and are used to increase the surface area of the small intestine. Villi are tiny microscopic folds in the small intestine lining. Microvilli are little hairlike projections from individual epithelial cells of the small intestine. They have capillaries and a lacteal that lead to the circulatory and lymph systems to transport nutrients that are absorbed.
