WebTools. The Hering–Breuer inflation reflex, named for Josef Breuer and Ewald Hering, [1] [2] [3] is a reflex triggered to prevent the over-inflation of the lung. Pulmonary stretch receptors present on the wall of bronchi and bronchioles of the airways respond to excessive stretching of the lung during large inspirations. WebThe Bohr Effect: The lower the partial pressure of CO2 in arterial blood, the lower the amount of oxygen hemoglobin will release to cells for energy. Once carbon dioxide is dissolved in the blood, carbonic acid is formed. …
