gas exchange
This term is a technical biological descriptor used primarily in medical, physiological, and anatomical contexts. It describes the passive diffusion of gases across a semi-permeable membrane, most commonly referring to the respiratory system in lungs or the gills of aquatic organisms.
Because it describes a continuous physiological process rather than a discrete object, it is treated as an uncountable noun. It is rarely pluralized and is typically paired with verbs like facilitate, impair, or optimize to describe the efficiency of the process.
