They detect changes in the arterial partial pressure of carbon dioxide (pCO 2).). When changes are detected, the receptors send impulses to the respiratory centres in the brainstem that initiate changes in ventilation to restore normal … WebSep 20, 2024 · Breathing Rate The rate at which we inhale and exhale is controlled by the respiratory centre, within the Medulla Oblongata in the brain.
