Anatomy and Physiology Questions
In physiology , respiration is the movement of oxygen from the outside environment to the cells within tissues , and the removal of carbon dioxide in the opposite direction. The physiological definition of respiration differs from the biochemical definition , which refers to a metabolic process by which an organism obtains energy in the form of ATP and NADPH 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 diffusion and transport of metabolites between the organism and the external environment.
Gas exchange in the lung occur by ventilation and perfusion. Inhalation breathing in is usually an active movement that brings air into the lungs where the process of gas exchange takes place between the air in the alveoli and the blood in the pulmonary capillaries. Contraction of the diaphragm muscle cause a pressure variation, which is equal to the pressures caused by elastic, resistive and inertial components of the respiratory system.
In contrast, exhalation breathing out is usually a passive process. The process of breathing does not fill the alveoli with atmospheric air during each inhalation about ml per breath , but the inhaled air is carefully diluted and thoroughly mixed with a large volume of gas about 2.
Physiological respiration involves the mechanisms that ensure that the composition of the functional residual capacity is kept constant , and equilibrates with the gases dissolved in the pulmonary capillary blood, and thus throughout the body.
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.

Examination Questions and Answers in Basic Anatomy and Physiology
Metrics details. A single-breath derecruitment maneuver was performed to assess recruitability. Invasive mechanical ventilation is required in most of the patients to treat gas exchange abnormalities and represents the mainstay of supportive therapy [ 4 , 7 , 9 ]. In this setting, mechanical ventilation is aimed at restoring adequate gas exchange while limiting ventilator-induced lung injury VILI [ 10 ]. During ARDS, proper ventilatory management reduces the risk of VILI and is among the potentially modifiable factors capable of improving survival [ 11 ]. The effects of ventilator settings tidal volume, positive end-expiratory pressure [PEEP] on VILI and clinical outcome are mediated by respiratory mechanics that have wide inter-individual variability [ 12 , 13 , 14 ]. Thorough understanding of respiratory mechanics is essential to limit the risk of VILI and, possibly, improve clinical outcome [ 15 , 16 ].
