High $pO_{2}$ and low $pCO_{2}$

Vedclass · Answer

(A) The partial pressure of gases in atmospheric air is $pO_{2} = 159 \; mmHg$ and $pCO_{2} = 0.3 \; mmHg$.In the alveoli,the partial pressure of gases is $pO_{2} = 104 \; mmHg$ and $pCO_{2} = 40 \; mmHg$.Comparing these values,the atmospheric air has a higher $pO_{2}$ $(159 \; mmHg > 104 \; mmHg)$ and a lower $pCO_{2}$ $(0.3 \; mmHg Therefore,the correct option is $A$.
