Villus, plural villi, in anatomy any of the small, slender, vascular projections that increase the surface area of a membrane. ... The villi of the small intestine project into the intestinal cavity, greatly increasing the surface area for food absorption and adding digestive secretions.
The tiny projections on the inner surface of the small intestine which help in absorbing the digested food are called villi. These helps to increase the surface area of intestinal walls.
These are located in the inner walls of the small intestine.
Their function is to increase the surface area of the small intestinal wall for absorption of the digested food.
These projections absorb the protein molecules and help in the transfer of the proteins to all cells and tissues.
Many blood vessels are present within these villi, that help in the absorption of digested food and carry it to the bloodstream. Later, from the bloodstream, the absorbed food is delivered to each and every cell of the body.
