Vedclass · Answer

(D) An efficient respiratory surface must facilitate the rapid diffusion of gases. According to Fick's Law of Diffusion,the rate of diffusion is inversely proportional to the thickness of the membrane. Therefore,a thin membrane is essential for efficient gas exchange. While moistness,large surface area,and rich blood supply are also important characteristics,the thinness of the membrane is a critical physical requirement for the diffusion process to occur effectively.

Which of the following factors is most necessary for an efficient respiratory surface?
