Simple diffusion

Vedclass · Answer

(A) The exchange of gases like $O_2$ and $CO_2$ at the alveolar membrane and between blood and tissues occurs primarily by the process of simple diffusion.Simple diffusion is a passive process driven by the partial pressure gradients of the gases.Since gases move from a region of higher partial pressure to a region of lower partial pressure without the expenditure of energy,it is classified as simple diffusion.

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

By which process does the exchange of gases take place in the body?

What will be the $pO_{2}$ and $pCO_{2}$ in atmospheric air as compared to alveoli?

$A$: Diffusion of carbon dioxide is $20$ times faster than oxygen.
$R$: It is due to difference in partial pressure as well as solubility of diffusing gases.

In humans,where does the exchange of gases take place?

The partial pressure of $O_{2}$ and $CO_{2}$ in atmospheric air as compared to those in alveolar air is:

Gas Alveolar Air $(X/A)$ Atmospheric Air $(Y/B)$

$pO_{2}$ $X$ $Y$

$pCO_{2}$ $A$ $B$
