WebThe pulmonary stretch receptors are nerves ending in the tracheal and bronchial smooth muscles. Their activity is enhanced by enlargement of airway cross-section, for example, when the lung volume increases, and results in an inhibition of further inspiratory activity. WebStretch receptors are situated in the walls of the atria, left ventricle and coronary arteries. Atrial receptors are stimulated by atrial distension due to increased filling as the result, amongst other things, of an increased blood volume. Their reflex responses are increases in heart rate and in urine flow.
