Vedclass · Answer

(B) The partial pressure of respiratory gases in the atmosphere and alveoli are as follows:$1$. For $O_{2}$, the partial pressure in atmospheric air is $159 \ mm \ Hg$, and in the alveoli, it is $104 \ mm \ Hg$ (represented as $A$).$2$. For $CO_{2}$, the partial pressure in atmospheric air is $0.3 \ mm \ Hg$, and in the alveoli, it is $40 \ mm \ Hg$ (represented as $B$).Therefore, $A = 104$ and $B = 40$.

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

Partial pressure (in $mm \ Hg$) of oxygen and carbon dioxide at different parts involved in diffusion in comparison to those in the atmosphere. Identify $A$ and $B$ and choose the correct option accordingly.
