Gas exchange in the lungs, blood and tissues

WebThe diffusion coefficient of gases is important when comparing different gases in the lung. Let's take CO2 and O2. They are similar in molecular weight, but CO2 is about 20x more … WebDiffusion is a process in which transport is driven by a concentration gradient. Gas molecules move from a region of high concentration to a region of low concentration.
