WebGas diffusion involves random molecular movement from areas of high partial pressure to areas of low partial pressure. The rate of diffusion depends on the partial pressure (or tension) difference between each area. The partial pressure (P) of a gas in a mixture is the pressure that a given gas would exert if it alone occupied the space.Partial pressures are … WebThe alveoli are adapted to make gas exchange in lungs happen easily and efficiently. Here are some features of the alveoli that allow this: The gases move by diffusion from …
