Simple diffusion

Vedclass · Answer

(A) The exchange of gases like $O_2$ and $CO_2$ in the lungs occurs across the alveolar membrane. This process is driven by partial pressure gradients. Since gases move from an area of higher partial pressure to an area of lower partial pressure without the expenditure of energy,this process is known as simple diffusion. Therefore,simple diffusion is the primary mechanism for gas exchange in the lungs.
