Chemoreceptors

 

 Chemoreceptors are chemosensitive cells which are sensitive to oxygen lack and excess in carbon dioxide and also hydrogen ion excess. These chemoreceptors are found in two bilateral (paired) carotid bodies and in three aortic bodies adjacent to the aorta. They are connected to carotid body nerves and vagus nerves which enter the medulla and reach the vasomotor center where they excite hypertensive response in order to manage peripheral low blood pressure.
