Vedclass · Answer

(C) The partial pressure of oxygen $(pO_2)$ varies in different parts of the respiratory system to facilitate gas exchange through diffusion.$1$. In the alveoli,the $pO_2$ is approximately $104 \; mm \; Hg$,which is higher than the $pO_2$ in the deoxygenated blood arriving at the lungs $(40 \; mm \; Hg)$,allowing oxygen to diffuse into the blood.$2$. In the systemic tissues,the $pO_2$ is approximately $40 \; mm \; Hg$,which is lower than the $pO_2$ in the oxygenated blood arriving from the lungs $(95 \; mm \; Hg)$,allowing oxygen to diffuse from the blood into the tissues.Therefore,the values are $104 \; mm \; Hg$ in the alveoli and $40 \; mm \; Hg$ in the tissues.
