Vedclass · Answer

(A) The exchange of gases like $O_2$ and $CO_2$ between the alveoli of the lungs and the blood,and between the blood and the tissues,occurs primarily by the process of simple diffusion. Diffusion is driven by the partial pressure gradients of these gases. Since the partial pressure of $O_2$ is higher in the alveoli compared to the blood,and higher in the blood compared to the tissues,$O_2$ moves from the lungs to the tissues via diffusion.
