How gas exchange happens
WebGas exchange during respiration occurs primarily through diffusion. Diffusion 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. Web13 sep. 2024 · How does smoking affect gas exchange? September 13, 2024 by Alexander Johnson. Smoking destroys the tiny air sacs, or alveoli, in the lungs that allow oxygen exchange. When you smoke, you are damaging some of those air sacs. Alveoli don’t grow back, so when you destroy them, you have permanently destroyed part of your lungs.
