respiration and respiratory systems. Inflation of the lungs in animals stops breathing by a reflex described by the German physiologist Ewald Hering and the Austrian physiologist Josef Breuer. The Hering-Breuer reflex is initiated by lung expansion, which excites stretch receptors in the airways. Stimulation of these receptors, which send signals to the medulla by the vagus nerve, shortens inspiratory times as tidal volume (the...
Histamine affects several receptors found in different tissues. Sometimes blocking the receptor and sometimes adding to it. Smooth muscle around bronchi in the lungs and within the intestinal tract respond to histamine stimulation by contraction, although the magnitude of response varies considerably among species. These effects also depend on which receptor is being bound by histamine; for example, the H2 receptor mediates bronchodilation.
