Vedclass · Answer

(D) The diffusion membrane is the structure through which gas exchange occurs in the lungs. It consists of three major layers: $1$. The thin squamous epithelium of the alveoli. $2$. The endothelium of the alveolar capillaries. $3$. The basement substance (basement membrane) in between them. Oxygen diffuses from the alveoli into the blood,and carbon dioxide diffuses from the blood into the alveoli through this membrane. The total thickness of this membrane is much less than a millimeter. Therefore,all the given statements are correct.
