What is the primary function of the baroreceptors located in the carotid sinus and aortic arch?
Monitor blood pressure changes
Baroreceptors are stretch-sensitive nerve endings located in the walls of the carotid sinus and the aortic arch.
They sense changes in arterial wall stretch, which reflect changes in blood pressure.
Signals travel via the glossopharyngeal (IX) and vagus (X) nerves to the medulla, triggering reflex changes in heart rate and vessel tone that keep blood pressure steady.
Gas exchange is done by alveoli, red cells are made in bone marrow and heart contractions are regulated by the SA node, none are the primary role of baroreceptors.
Hence, Monitor blood pressure changes.
