Vedclass · Answer

(A) The partial pressure of oxygen $(PO_2)$ varies in different parts of the respiratory system to facilitate diffusion:$1$. In atmospheric air, the $PO_2$ is approximately $159\, mm\, Hg$.$2$. In oxygenated blood (systemic arteries), the $PO_2$ is approximately $95\, mm\, Hg$.$3$. In tissues, where oxygen is consumed for cellular respiration, the $PO_2$ is low, approximately $40\, mm\, Hg$.Therefore, the correct matching is: $P-I, Q-III, R-II$.

Column-$I$	Column-$II$ ($PO_2$ in $mm\, Hg$)
$P$. Atmospheric air	$I$. $159$
$Q$. Tissues	$II$. $95$
$R$. Oxygenated blood	$III$. $40$
