What does respiratory mean?
Respiratory is an adjective meaning connected with breathing or with the organs and processes that bring air into and out of the body. It is especially common in medical and scientific contexts, where it describes the respiratory system, respiratory infections, respiratory illness, respiratory distress, and respiratory disease. The term can refer to the overall breathing process, as in “respiratory health,” or to particular structures and functions involved in respiration. It is useful because it identifies the body’s essential exchange of oxygen and carbon dioxide while remaining broad enough for general audiences. Although related to the more process-focused term respiration and the verb respire, respiratory is used when a quality, condition, or category is being described.
