- Villi are millions of tiny finger-like projections that constitute the mucosal wall of the small intestine.
- The surface area of these villi increases, allowing more nutrients to be absorbed.
- The small intestine contains villi, which enhance the absorption surface area.
- Because digestion is not yet complete in the stomach, there is no point in absorption, but digestion is complete in the small intestine, resulting in maximal nutritional absorption.
