WebThe lungs are specifically adapted for gas exchange (diffusion) - meaning the lungs allow oxygen into the blood stream and carbon dioxide out. To ensure our cells can respire properly, we want fast and efficient gas exchange. The lungs contain many 'tubes' or airways that carry air in and out of our lungs.
