WebGas Exchange Our bodies need to bring in oxygen and get rid of excess carbon dioxide. This process is called gas exchange. Gas exchange occurs at two sites in the body: In the lungs, where oxygen is picked up and carbon dioxide is released at the respiratory membrane. This is called external respiration. WebGas exchange, the intake of molecular oxygen (O 2) from the environment and the outflow of carbon dioxide (CO 2) into the environment, is necessary for cellular function. Gas exchange during respiration occurs largely via the movement of gas molecules along pressure gradients. charles claybrook stoneville nc https://nt-guru.com
