The main purpose of this is to get oxygen into the cells of the body where it can be used in the process of respiration to generate energy from glucose. Other chemicals such as nicotine can also easily pass through the thin walls of these air sacs (aveoli) as can viruses and microorganisms. Hope that helps Diesel 'Danger' Nutkins

The capillaries are the small blood vessels that surround each alveolus, or air sac.
Why must air sacs have thin walls?

What gases are exchanges in air sacs?
The air sacs (alveoli) have a very large total surface area and a very good blood supply. There is an exchange of gases between the air sacs and their surrounding capillary blood vessels. Oxygen diffuses from the air sac into the blood. Carbon dioxide diffuses from the blood into the air sac.
