How gas exchange happens

WebThe partial pressure of any gas can be calculated by: (39.1) P = (P atm ) × (percent content in mixture). P atm, the atmospheric pressure, is the sum of all of the partial pressures of the atmospheric gases added together, (39.2) P atm = P N2 + P O2 + P H2O + P CO2 = 760 mm Hg. × (percent content in mixture). Gas exchange is the physical process by which gases move passively by diffusion across a surface. For example, this surface might be the air/water interface of a water body, the surface of a gas bubble in a liquid, a gas-permeable membrane, or a biological membrane that forms the boundary between an organism and its extracellular environment. Gases are constantly consumed and produced by cellular and metabolic reactions in most living …
