Key points. There are three main gases in air that are taken in and removed from the body. These are oxygen, nitrogen and carbon dioxide. Gas exchange is the ‘swapping’ of gasses - absorbing...

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, and at the tissues, where oxygen is released and carbon dioxide is picked up.

Gases that do not react chemically with cell cytoplasm are called inert gases; these include nitrogen, helium, and anesthetic gases. They diffuse so rapidly that their rate of equilibration with tissues cannot be measured directly by experiment.
Nov 21, 2023 · When we refer to inert gases, we are usually referring to six primary ones, also called the noble gases. Meet the most common inert gases: helium (He), argon (Ar), neon (Ne), krypton (Kr), xenon...
