Learn more about their structure, role and diagram, and check related biology questions and solutions. What are villi ? What is their location and function? Answer: After the pancreatic juice acts on carbohydrates, fat and proteins, the digested food passes into the blood vessels in the wall of the intestine. This process is called Absorption . The inner wall of the small intestine has many finger-like outgrowths called villi . These increase the surface area of the small intestine, hence increasing absorption .
