Vedclass · Answer

(D) The partial pressure of carbon dioxide $(pCO_2)$ varies in different parts of the respiratory system to facilitate gas exchange. Based on standard physiological values:$1$. In atmospheric air,the $pCO_2$ is approximately $0.3 \; mm \; Hg$.$2$. In the alveoli,the $pCO_2$ is $40 \; mm \; Hg$.$3$. In the tissues,where metabolic activity produces $CO_2$,the $pCO_2$ is $45 \; mm \; Hg$.Therefore,the correct sequence is $0.3 \; mm \; Hg, 40 \; mm \; Hg$,and $45 \; mm \; Hg$.

What is the value of $pCO_2$ in atmospheric air,alveoli,and tissues respectively?
