Solution
The correct option is A Simple diffusion
Exchange of gases in lungs occurs through simple diffusion. In this gaseous exchange, oxygen passes from the alveoli into the pulmonary capillary blood and carbon dioxide comes to alveoli from the pulmonary capillary. Exchange of gases through the alveolocapillary membrane is a purely physical diffusion phenomenon, no chemical reaction is involved.
