Stretch receptors in lungs

WebAt inspiration, the increased lung volume stimulates or activates the stretch receptors on the smooth muscles of the bronchi and trachea. The signal from the stretch receptor stimulation is processed by the brain, which then mediates the inhibition of the outflow of efferent vagus motor neurons of the heart's sinoatrial (SA) node, resulting in ...
