Given below are two statements: One is labelled as Assertion A and the other is labelled as Reason R.
Assertion A: During the transportation of gases, about 20-25 percent of CO$$_2$$ is carried by Haemoglobin as carbamino-haemoglobin.
Reason R: This binding is related to high pCO$$_2$$ and low pO$$_2$$ in tissues.
In the light of the above statements, choose the correct answer from the options given below.
Match List I with List II:
| List - I | List - II | ||
|---|---|---|---|
| A. | Expiratory capacity | I. | Expiratory reserve volume + Tidal volume + Inspiratory reserve volume |
| B. | Functional residual capacity | II. | Tidal volume + Expiratory reserve volume |
| C. | Vital capacity | III. | Tidal volume + Inspiratory reserve volume |
| D. | Inspiratory capacity | IV. | Expiratory reserve volume + Residual volume |
Choose the correct answer from the options given below :
Which of the following factors are favourable for the formation of oxyhaemoglobin in alveoli?
Select the sequence of steps in Respiration.
(A) Diffusion of gases (O2 and CO2) across alveolar membrane.
(B) Diffusion of O2 and CO2 between blood and tissues.
(C) Transport of gases by the blood
(D) Pulmonary ventilation by which atmospheric air is drawn in and CO2 rich alveolar air is released out.
(E) Utilisation of O2 by the cells for catabolic reactions are resultant release of CO2
