Question

Quizplus · Accepted Answer

All of the choices listed facilitate gas exchange in the lungs.

A - The fusion of the basement membranes of alveolar epithelium and adjacent capillaries allows for more efficient diffusion of gases across the membrane.

B - The short distance between the respiratory and circulatory systems allows for faster and more efficient exchange of gases.

C - The lipid solubility of gases allows them to diffuse through the phospholipid bilayer of the respiratory membrane.

D - Diffusion is the process by which gases move from an area of high concentration to an area of low concentration, which is how gas exchange occurs in the lungs.

Therefore, all of the answers are correct.
