Prize share: 1/1
Without conscious thought on our part, our breathing is regulated by a respiratory center in the medulla oblongata. Corneille Heymans, his father and colleagues researched how breathing is regulated by muscular reflexes and the blood's chemical composition. Through work with dogs, they showed how impulses are conveyed via the vagus nerves between the respiratory center and respiratory muscles. In 1931 Corneille Heymans demonstrated that the glomus, a small globular body made up of small blood vessels from the carotid artery, has an important role in this context through readings of the blood's chemical composition.
