    Answer:

Villi are micro-tentacles that line the inside of the walls of the small intestine. They are like tiny hair and are invisible to the naked eye. The villi have blood vessels and muscle that they use to wiggle and further mix the nutrients traveling along the intestinal wall. The villi movements cause the fluid to swirl in different directions. This motion produces numerous small eddies and interactions leading to improved digestion and nutrients absorbing.
