Explanation:
Detailed explanation-1: -Three processes are essential for the transfer of oxygen from the outside air to the blood flowing through the lungs: ventilation, diffusion, and perfusion. Ventilation is the process by which air moves in and out of the lungs.
Detailed explanation-2: -Features of Gas Exchange Surfaces Thin walls to ensure diffusion distances remain short. Good ventilation with air so that diffusion gradients can be maintained. Good blood supply to maintain a high concentration gradient so diffusion occurs faster.
