Explain how respiration is regulated in the event of increased CO2
Central and peripheral chemoreceptors (Aortic/Carotid) detect increase in blood CO2. Detected by inspiratory centre in Medulla Oblongata and sends nerve impulses to inspiration/exhalation muscles. Causes more forceful/frequent inhalation/exhalation.
