(A) Diffusion of gases across alveolar membrane.
(B) Diffusion of and between blood and tissues.
(C) Transport of gases by the blood.
(D) Pulmonary ventilation by which atmospheric air is drawn in and rich alveolar air is released out.
(E) Utilisation of by the cells for catabolic reactions and resultant release of .
Choose the correct answer from the options given below :
Options
- A(B), (C), (E), (D), (A)
- B(A), (C), (B), (E), (D)
- C(D), (A), (C), (B), (E)
- D(C), (B), (A), (E), (D)
Correct answer
C. (D), (A), (C), (B), (E)
Step-by-step solution
Option (3) is the answer, because the respiration involves the following stages:
1. Breathing or pulmonary ventilation by which atmospheric air is drawn in and rich alveolar air is released out.
2. Diffusion of gases across alveolar membrane.
3. Transport of gases by the blood.
4. Diffusion of and between blood and tissue.
5. Utilisation of by the cells for catabolic reactions and resultant release of
Rest of options (1), (2) and (4) are not the answers because these steps are not arranged in the correct sequence.
