Solution

Q.
The partial pressures (in mm Hg) of oxygen ( $O_{2}$ ) and carbon dioxide ( ${CO}_{2}$ ) at alveoli (the site of diffusion) are [2021]

1 ${pO}_{2}$ = 159 and ${pCO}_{2}$ = 0.3

2 ${pO}_{2}$ = 104 and ${pCO}_{2}$ = 40

3 ${pO}_{2}$ = 40 and ${pCO}_{2}$ = 45

4 ${pO}_{2}$ = 95 and ${pCO}_{2}$ = 40

Ans.
(2)

The partial pressure (in mm Hg) of oxygen and carbon dioxide at alveoli are 104 and 40 respectively.
