Surfaces where O2 diffuses into the blood and CO2 diffuses out of the blood. Each lung contains millions of these sacs. The small round alveoli allow for an amazingly large surface area for this gas exchange to take place. ... Therefore, the greater the surface area, the more gas exchange can occur.
