Describe how the lungs are adapted for gas exchange (6 marks)

WebThe lungs contain lots of alveoli, and each one is microscopic. The alveoli are the sites of gas exchange. Oxygen in the air diffuses into the blood stream and carbon dioxide diffuses into the air. The alveoli are adapted to make the rate of gas exchange as fast as possible.
