Webb1 aug. 1999 · Although feedback from pulmonary stretch receptors and direct respiratory-related changes in venous return and cardiac stretch can evoke respiratory related fluctuations in heart rate, the dominant source of respiratory sinus arrhythmia originates from the brain stem ( 2 ). WebbPulmonary 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. Webb17 dec. 2002 · Since the original work by Hering and Breuer on slowly adapting pulmonary stretch receptors (SARs), numerous studies have demonstrated that these receptors are the lung vagal afferents responsible for eliciting the reflexes evoked by moderate lung inflation.SARs play a role in controlling breathing pattern, airway smooth muscle tone, … small days lyrics

P2Y receptors were found in the pulmonary arteries of various species. Thus, mRNA expression of P2Y1, P2Y2, P2Y4, P2Y6, ...

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] Webb1 juli 2003 · Pulmonary stretch receptors were activated by tonically inflating the lungs with air, achieved by setting the outflow pressure at either 1 or 10 cmH 2 O. Tests were not conducted until 3–5 min after changes in tracheal pressure, to avoid potential influences of phasic changes in pulmonary volume.

WebbCapsaicin was injected intravenously to stimulate lung C-fibre receptors, and veratrine to stimulate pulmonary stretch receptors and cardiac receptors . Acetazolamide treatment (20 mg/kg) diminished the inhibitory responses of slowly adapting pulmonary stretch receptors to CO2 inhalation , which were not significantly influenced by pretreatment …
