Villus or Villi are the small finger-like projections on the inner wall of the small intestine. Villi contain microvilli which increase the surface area of the intestinal walls for absorption. The villi have a thin wall made up of a single layer of epithelial cells and also have a rich supply of blood and lymph capillaries. This helps in rapid absorption of digested nutrients from the lumen of the small intestine into the blood or lymph circulation.
