1) Central regulatory centres : A) Pontine centers - Pneumotaxic centre (upper pons) → ↓ respiratory rate. - Apneustic centre (lower pons) → ↑ respiratory rate. B) Medullary respiratory centers (inspiratory & expiratory centers) 2) Chemoreceptors : A) Central: raised [H+] in ECF stimulates respiration B) Peripheral: carotid + aortic bodies, respond to raised pCO2 & [H+], lesser extent low pO2 3) Pulmonary receptors : A) Stretch receptors : lung distension causes slowing of respiratory rate (Hering- Bruer reflex) B) Irritant receptor : leading to bronchoconstriction C) Juxtacapillary receptors : stimulated by stretching of the microvasculature
