Process that begins gas exchange
Did you know?
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 t… WebbGas exchange is the physical process by which gases move passively, meaning that no energy is required to power the transport, by diffusion across a surface..
