WebbFurther complexity arises from the CO (2)-sensitive nature of the pulmonary stretch receptors (PSR) which provide both tonic (stimulates lung inflation at low lung volumes; deflation at higher volumes) and phasic (generally excitatory) feedback. WebbAlthough their functional role is unclear, J-receptors respond to events such as pulmonary edema, pulmonary emboli, pneumonia, congestive heart failure and barotrauma, which cause a decrease in oxygenation and thus lead to an increase in respiration. [2] how does our solar system moveWebbPulmonary stretch receptors are thought to mediate the breathing frequency (bf) response to changes in pulmonary CO2. However, the location and distribution of these receptors is disputed. The purpose of this study was to determine what contribution the extrapulmonary receptors make in the pulmonary CO2 bf response. how does our family wizard work

The pulmonary stretch receptors

WebbIt appears that in diving the decrease in pulmonary stretch receptor activity during apnea, combined with cessation of central inspiratory neuronal drive, is an important integrative mechanism that helps development of the reflex bradycardia of trigeminal, carotid, chemoreceptor, and baroreceptor origin. Publication types WebbSlowly adapting (pulmonary stretch) receptors (SARs) are mechanoreceptors that lie within the submucosal smooth muscles in the membranous posterior wall of the trachea and central airways (Bartlett et al., 1976). A small proportion of the receptors are located in the extrathoracic upper trachea (Berger, 2000).
