The chemoreceptor reflex responds to increased CO2 or decreased pH by activating chemoreceptors, which signal the cardiac and vasomotor centers to increase cardiac output and cause vasoconstriction, thus raising blood pressure.
1. Rise in CO2/drop in pH activates chemoreceptors in aortic arch and carotid sinus 2. Chemoreceptor input to cardiac center and vasomotor center causes increased cardiac output and vasoconstriction 3. Rise in BP will speed the return of blood to heart and lungs
