Vedclass · Answer

(D) The diffusion membrane is composed of three major layers: the thin squamous epithelium of alveoli,the endothelium of alveolar capillaries,and the basement substance in between them.These layers are extremely thin,and the total thickness of the diffusion membrane is much less than a millimeter $(This minimal thickness is crucial for the efficient diffusion of gases ($O_2$ and $CO_2$) across the membrane.

What is the thickness of the diffusion membrane involved in the exchange of gases in the lungs?

The partial pressures (in $mm \ Hg$) of oxygen $(O_{2})$ and carbon dioxide $(CO_{2})$ at the alveoli (the site of diffusion) are:

What is the value of $pO_2$ in alveoli and tissues respectively?

The solubility of $CO_2$ is about $.......$ times higher than that of oxygen across the respiratory membrane.

Why do human beings face difficulty breathing at high elevations?

$A$: 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.
