Breathing is the process that moves air in and out of the lungs, to allow the diffusion of oxygen and carbon dioxide to and from the external environment into and out of the blood. Breathing sometimes also refers to the equivalent process using other respiratory organs such as gills in fish and spiracles in certain arthropods. For organisms with lungs, breathing is also called pulmonary ventilation, which consists of inhalation (breathing in) and exhalation (breathing out).
