The alveoli are the sites of gas exchange in the lungs. They are round and numerous, so the surface area is maximised for increased volumes of oxygen and carbon dioxide to pass through. Their membranes are very thin, and they are surrounded by a network of capillaries to further increase the efficiency of the gas exchange process.

The alveoli basically serves as a barrier between the blood and the air, through which air can easily pass through and be taken up by the blood.
