Question

(B) In the human respiratory system,the partial pressure of gases in the alveoli is essential for the exchange of gases between the blood and the lung

Vedclass · Accepted Answer

$PO_2 = 104 \, mm \, Hg$ and $PCO_2 = 40 \, mm \, Hg$

Vedclass · Answer

(B) In the human respiratory system,the partial pressure of gases in the alveoli is essential for the exchange of gases between the blood and the lungs.- The partial pressure of Oxygen $(PO_2)$ in the alveoli is approximately $104 \, mm \, Hg$.- The partial pressure of Carbon dioxide $(PCO_2)$ in the alveoli is approximately $40 \, mm \, Hg$.- These values create a concentration gradient that allows $O_2$ to diffuse into the blood and $CO_2$ to diffuse out of the blood into the alveoli for exhalation.- Therefore,option $B$ is the correct answer.

Gas	Atmospheric Air	Alveoli
$O_{2}$	$159$	$A$
$CO_{2}$	$0.3$	$B$
