Chemoreceptors operate between pressure range of:
In nervous circulatory mechanism of aerial BP the chemoreceptor reflex operates between 40-100 mm Hg . Fallen the aerial BP less than 80 mmhg decreases blood flow to the tissues this decreases pO2 2 carotid and aoic bodies and causes stimulation of VMC and CVC and respiratory centre.
