4. Chemosenstive centredue to increase in C02 and H+ can signal therhythm centre to make adjustment to eliminate these substances.
5. Receptors associatedwith aortic arch and carotid artery also can recognise changes in CO2 andH+ concentration and send necessary signals to rhythm centrefor remedial actions.
