How are oxygen and carbon dioxide exchanged
WebThe main site of exchange of gases is alveoli. The gases are exchanged between tissues and blood. Carbon dioxide and oxygen are exchanged in these site by simple diffusion on the basis of pressure or concentration gradients. Two important factors that influence the rate of diffusion are: The solubility of the gases. The thickness of the membranes.
