Vedclass · Answer

(C) The exchange of gases ($O_2$ and $CO_2$) occurs by simple diffusion based on pressure gradients.$1$. For $O_2$,the partial pressure is higher in the alveoli $(104 \ mmHg)$ compared to the deoxygenated blood $(40 \ mmHg)$,creating a gradient from lungs to tissues.$2$. For $CO_2$,the partial pressure is higher in the tissues $(45 \ mmHg)$ compared to the blood $(40 \ mmHg)$ and alveoli $(40 \ mmHg)$,creating a gradient from tissues to lungs.$3$. Therefore,the concentration gradient for $CO_2$ is from tissues to lungs,and for $O_2$ is from lungs to tissues.

Gas	Alveolar Air $(X/A)$	Atmospheric Air $(Y/B)$
$pO_{2}$	$X$	$Y$
$pCO_{2}$	$A$	$B$
