-as of [22 FEBRUARY 2024]–
.
-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 biochemical definition, which refers to cellular respiration, a metabolic process by which an organism obtains energy (in the form of ATP) by oxidizing nutrients and releasing waste products)
(although physiologic respiration is necessary to sustain cellular respiration and thus life in animals, the processes are distinct: cellular respiration takes place in individual cells of the organism, while physiologic respiration concerns the bulk flow and transport of metabolites between the organism and the external environment)
(gaseous exchange (which in organisms with lungs is called ‘ventilation’ and includes inhalation and exhalation) is a part of physiologic respiration)
.
(thus, in precise usage, the words “breathing” + “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)
