Vedclass · Answer

(D) The rate of diffusion of gases across the respiratory membrane is governed by Fick's Law of Diffusion.Factors affecting this rate include:$1$. Solubility of the gas: Gases with higher solubility (like $CO_2$) diffuse more rapidly than those with lower solubility (like $O_2$).$2$. Partial pressure gradient: The difference in partial pressure between the alveoli and the blood drives the diffusion.$3$. Thickness of the respiratory membrane: The thinner the membrane, the faster the diffusion rate.Since all these factors influence the rate of diffusion, the correct option is $D$.

The rate of diffusion of gases can be affected by $-$

Which structure of the lungs is directly involved in $O_2 / CO_2$ exchange between air and blood capillary?

What are the partial pressures of oxygen $(PO_2)$ and carbon dioxide $(PCO_2)$ in the alveolar air?

$A$: 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.
