The lungs itself don't exchange the gases; there are many, many air sacs in the lungs, which exchange the gases. So when carbon dioxide goes in to the air sacs, the oxygen rushes in and the carbon dioxide goes out, which we exhale. This is called diffusion.

♤ In the lungs, the air passage that divides into smaller and smaller tubes called bronchi which form bronchioles .

♤ The bronchioles terminate in the balloon like structure called alveoli.

♤ The alveoli present in the lungs provide maximum surface for exchange of gases.

♤ The alveoli have very thin walls and contain an extensive network of blood vessels to facilitate exchange of gases.
