WebThe Hering-Breuer reflex is mediated by stretch and irritant receptors. The function of stretch receptors is to increase inspiratory flow and tidal volume without changing inspiration time (Haddad and Mellins, 1977). This means that stretch receptors increase the output of the respiratory center. The function of irritant receptors is to shorten ...

WebJan 1, 1981 · Pulmonary stretch receptors. The pulmonary stretch receptors are located in the smooth muscle or lamina propria of the airways. The natural stimulus for these endings is inflation of lungs; the activity increases in phase with inspiration and may diminish or cease altogether during exspiration. These receptors mediate two important reflexes: /l ... WebPeripheral chemoreceptors (carotid and aortic bodies) and central chemoreceptors (medullary neurons) primarily function to regulate respiratory activity. This is an important mechanism for maintaining arterial blood pO2, pCO2, and pH within appropriate physiological ranges. For example, a fall in arterial pO2 ( hypoxemia) or an increase in ... WebFunction; Medullary respiratory center: Sets the basic rhythm of breathing: Ventral respiratory group (VRG) Generates the breathing rhythm and integrates data coming into the medulla: Dorsal respiratory group (DRG) Integrates input from the stretch receptors and the chemoreceptors in the periphery: Pontine respiratory group (PRG) body extortion

Pulmonary Stretch Receptors - an overview

WebAs the main aim of the reflex mechanisms is to control the arterial blood pressure (BP), their action is based primarily on signals from baroreceptors, although they also reflect the activity of pulmonary stretch receptors and, to a lower degree, chemoreceptors, with different mechanisms acting either in synergism or in antagonism depending on ... WebPulmonary arterial hypertension (PAH), group 1 pulmonary hypertension (PH), is a fatal disease that is characterized by vasoconstriction, increased pressure in the pulmonary arteries, and right heart failure.
