WebThe 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/ Hering-Breuer inflation reflex. WebMechanoreceptors monitor the expansion of the lung, the size of the airway, the force of respiratory muscle contraction, and the extent of muscle shortening. Although the … ferring wiki
