Villi are adapted for material exchange by increasing surface area for rapid nutrient absorption into the blood, possessing a single layer of surface cells, and having a rich blood supply.
The villi is adapted to exchanging materials as it increases surface area so digested food is absorbed much more quickly into blood, have a single layer of surface cells and a very good blood supply to assist quick absorption.
