$pO_{2}$ higher,$pCO_{2}$ lesser

Vedclass · Answer

(A) The correct answer is $A$.The partial pressure of oxygen $(pO_{2})$ in atmospheric air is higher than that of oxygen in alveolar air. In atmospheric air,$pO_{2}$ is approximately $159 \, mm \, Hg$,whereas in alveolar air,it is about $104 \, mm \, Hg$.The partial pressure of carbon dioxide $(pCO_{2})$ in atmospheric air is significantly lower than that of carbon dioxide in alveolar air. In atmospheric air,$pCO_{2}$ is about $0.3 \, mm \, Hg$,while in alveolar air,it is approximately $40 \, mm \, Hg$.
