Alveoli are in the lungs (gas exchange) and Villi are in the small intestine (food absorption).
The reason why they're well adapted for gas exchange and food absorption is:

-They have a thin exchange surface so that the diffusion pathway is very small and quick.
-They have a large surface area.
-They are covered with capillaries which are needed for the exchange or absorption.
-There are many alveoli and villi in the body.

If you have questions about these 4 features, please ask and i'll explain them in detail.
