What is a Villi and how does what it does relate to what it looks like?
The lining of the small intestine contains many folds. These folds increase the surface area that can be in contact with the food products. The lining surface of the intestinal folds is further increased by many microscopic fingerlike projections called villi. The digested food is passed through the cell membranes of the villi into the blood and lymph, which carry it to the cells. The body can then use the food for energy and growth.
