Select the sequence of steps in Respiration. (A) Diffusion of gases ($O_2$ and $CO_2$) across alveolar membrane. (B) Diffusion of $O_2$ and $CO_2$ between blood and tissues. (C) Transport of gases by the blood (D) Pulmonary ventilation by which atmospheric air is drawn in and $CO_2$ rich alveolar air is released out. (E) Utilisation of $O_2$ by the cells for catabolic reactions are resultant release of $CO_2$. Choose the correct answer from the options given below:
A
(D), (A), (C), (B), (E)
B
(C), (B), (A), (E), (D)
C
(B), (C), (E), (D), (A)
D
(A), (C), (B), (E), (D)
Detailed Solution
The correct sequence of respiration: Pulmonary ventilation (D) → Diffusion of gases across the alveolar membrane (A) → Transport of gases by blood (C) → Diffusion of gases between blood and tissues (B) → Utilisation of $O_2$ by cells for catabolic reactions (E). Order: D, A, C, B, E.
