Quizplus · Accepted Answer

Chemoreceptors that help regulate breathing can be found in both the carotid artery and aorta, as well as in the medulla oblongata. The chemoreceptors in the carotid artery and aorta detect changes in the levels of oxygen, carbon dioxide, and pH in the blood, and signal the brain to adjust breathing rate and depth accordingly. The chemoreceptors in the medulla oblongata respond to changes in the pH of cerebrospinal fluid and help regulate breathing rhythm.
