gas exchange
gas exchange In biology, the uptake and output of gases, especially oxygen and carbon dioxide, by living organisms. In animals and other organisms that obtain their energy by
aerobic respiration, gas exchange involves the uptake of oxygen and the output of carbon dioxide. In plants, algae and bacteria that carry out
photosynthesis, the opposite may occur, with a carbon dioxide uptake and oxygen output. At the cellular level, gas exchange takes place by
diffusion across cell
membranes in solution. See also
