(A) Exchange of gases in the lungs is known as external respiration.In this process,oxygen moves from the alveoli into the pulmonary capillary blood,while carbon dioxide moves from the pulmonary capillaries into the alveoli.The exchange of gases across the alveocapillary membrane is a purely physical process known as simple diffusion.This process is driven by partial pressure gradients and does not involve any active transport or chemical reactions.
