Respiration involves the following steps

(i) Breathing or pulmonary ventilation by which atmospheric air is drawn in and  rich alveolar air is released out

(ii) Diffusion of gases, i.e.,  and  across alveolar membrane

(iii) Transport of the gases by blood

(iv) Diffusion of  and  between the blood and tissue

(v) Utilisation of  by the cells for catabolic reactions and the resultant release of
