Respiration (physiology)

In physiology, respiration is defined as the movement of oxygen from the outside air to the cells within tissues, and the transport of carbon dioxide in the opposite direction.

The physiological definition of respiration should not be confused with the bulk flow and transport of metabolites between the organism and the external environment.

ventilation and includes inhalation and exhalation) is a part of physiologic respiration. Thus, in precise usage, the words breathing and ventilation are hyponyms, not synonyms, of respiration; but this prescription is not consistently followed, even by most health care providers, because the term respiratory rate (RR) is a well-established term in health care, even though it would need to be consistently replaced with ventilation rate if the precise usage were to be followed.
