For completion of respiration process, write the given steps in sequential manner
a. Diffusion of gases (O2 and CO2) across alveolar membrane.
b. Transport of gases by blood.
c. Utilisation of O2 by the cells for catabolic reactions and resultant release of CO2.
d. Pulmonary ventilation by which atmospheric air is drawn in and CO2 rich alveolar air is released out.
e. Diffusion of O2 and CO2 between blood and tissues.
The correct sequence would be:
1. Pulmonary ventilation by which atmospheric air is drawn in and CO2 rich alveolar air is released out.
2.Diffusion of gases (O2 and CO2) across alveolar membrane.
3.Transport of gases by blood.
4.Diffusion of O2 and CO2 between blood and tissues.
5.Utilisation of O2 by the cells for catabolic reactions and resultant release of CO2.
So, the correct sequence would be d,a ,b, e and c.
