The level of CO2 in the blood is detected by chemoreceptors located in the aortic arch and carotid arteries. These send impulses to either the cardioaccelerator or
cardioinhibitor center in the hypothalamus of the brain, which in turn sends an
impulse to the pacemaker of the heart to increase or decrease heart rate. Draw a
feedback diagram to illustrate what happens to restore homeostasis when blood CO2
rises.
