The partial pressure (in mm Hg) of oxygen (O2) and carbon dioxide (CO2) at alveoli (the site of diffusion) are:

A

`pO_(2)=40` and `pCO_(2)=45`

B

`pO_(2)=95` and `pCO_(2)=40`

C

`pO_(2)=159` and `pCO_(2)=0.3`

D

`pO_(2)=104` and `pCO_(2)=40`

Text Solution

Verified by Experts

The correct Answer is:
D
• In the alveolar air, the partial pressures of oxygen `(pO_(2))` is 104mm Hg and that of carbon dioxide `(pCO_(2))` is 40mm Hg.
