Pulmonary irritant receptors

WebThe laryngeal and pulmonary irritant receptors and pulmonary stretch receptors are affected by inhalation agents. Pulmonary stretch receptors are located in the small airway smooth muscle and respond to changes in stretching or changes in lung volume. WebChemoreceptors. One way in which breathing is controlled is through feedback by chemoreceptors. There are two kinds of respiratory chemoreceptors: arterial chemoreceptors, which monitor and respond to changes in the partial pressure of oxygen …
