What are villi? What is their location and function?

Answers (2)

The inner walls of the small intestine have thousands of finger-like outgrowths. These are called villi (singular villus). 

The villi increase the surface area for absorption of the digested food. The surface of the villi absorbs the digested food materials. The absorbed substances are transported via the blood vessels to different organs of the body where they are used to build complex substances such as the proteins required by the body. This is called assimilation
