HEYAAA MATE.☺️☺️☺️

HERE IS UR ANSWER....

THE ROLE OF VILLI IS ABSORPTION ..

When the food has been broken down into nutrients, vitamins. proteins etc. from the stomach to the small intestine, villi lines the intestine and the villi absorbs the nutrients and vitamins which will be used by the body.

THE ROLE OF ALVEOLI...

The function of the alveoli is to get oxygen into the blood stream for transport to the tissues, and to remove carbon dioxide from the blood stream.
