Quizplus · Accepted Answer

Both the aorta and carotid arteries have both chemoreceptors and baroreceptors associated with respiratory autonomic reflexes. The aortic and carotid bodies sense changes in oxygen, carbon dioxide, and pH levels in the blood and send signals to the respiratory center in the brainstem to adjust the breathing rate and depth. The baroreceptors in these arteries detect changes in blood pressure and also influence respiratory reflexes. The lungs have stretch receptors that are also involved in respiratory reflexes but do not have chemoreceptors or baroreceptors.
