Solution

The correct option is A (iii), (vi), (ii), (v), (i), (iv)
The sequence of steps of respiration is:
Pulmonary ventilation by which atmospheric air is drawn in and $C O_{2}$ is released out.
Diffusion of gases (O $_{2}$ and CO $_{2}$ ) across alveolar tissues.
Transport of gases by the blood.
Diffusion of O $_{2}$ and CO $_{2}$ between blood and tissues.
The utilization of O $_{2}$ by the cells for catabolic reactions.
Released resultant CO $_{2}$ .
So, the correct answer is '(iii), (vi), (ii), (v), (i), (iv)'.
