If the respiratory rate of ‘A’ is 35 breaths/min and tidal volume 185 cc/breath and of ‘B’ is 25 breaths/min and tidal volume 259 cc/breath then
(a) Pulmonary ventilation of ‘A’ and ‘B’ is same.
(b) Alveolar ventilation of ‘A’ and ‘B’ is same.
(c) Pulmonary ventilation of ‘A’ is greater than ‘B’.
(d) Alveolar ventilation of ‘A’ is greater than ‘B’.

(c) Pulmonary ventilation of ‘A’ is greater than ‘B’.
Explanation:
The process by which a continuous exchange of gases is maintained across respiratory surface is often called external respiration. The ventilation rate of an animal is the volume of air breathed per minute i.e tidal volume x number of breathes per minute. It can be measured with the aid of a respirometer.
