Explanation:
It is the exchange of gases by diffusion between alveoli and blood in blood vessel, across respiratory membrane. During inspiration, oxygen is taken into the lungs. The partial pressure of oxygen in lungs is higher than that in blood capillaries. Therefore, oxygen diffuses from the lungs to the blood.
