WebMay 24, 2024 · The first is the cardio accelerator center that increases the heart rate and stroke volume (if there is enough blood) in reaction to the signals of the sympathetic (fight or flight) nervous system. The second is the cardio inhibitor center that slows the heart rate and stroke volume under parasympathetic (rest and digest) influence. • Carotid bodies and aortic bodies detect changes primarily in pCO2 and H ion concentration. They also sense decrease in partial pressure of O2, but to a lesser degree than for pCO2 and H ion concentration. • The chemoreceptor trigger zone is an area of the medulla in the brain that receives inputs from blood-borne drugs or hormones, and communicates with the vomiting center (area postrema) to induce vomiting.
