Question

Alveoli are the terminal air sacs of the lungs, and are the sites of gas exchange between the lungs and blood. How does the surface area-to-volume ratio of the cells of alveolar walls relate to their function? please hurry.

Answer 1

Alveoli are specifically designed to quickly facilitate the exchange of gas from the lungs to the blood. They are very small, but with a very high surface area allowing a greater amount of gases to be exchanged in a comparatively short period of time.
