Diffusion within the lungs
WebThe data in the above table clearly shows that there is a concentration gradient for O 2 from the alveoli to blood and blood to tissues.Similarly, CO 2 has a concentration gradient in the opposite direction i.e. from tissues to blood and blood to the alveoli. The amount of CO 2 that can diffuse through a membrane is much higher than that of O 2 since the solubility …
