Answer:
These are called chemoreceptors, because they respond to specific chemicals. The are located in depressions in the walls of the aorta and the internal carotid arteries. These locations are referred to as the aortic and carotid sinuses. They respond by sending impulses to appropriate centers in the brainstem, which then speed up or slow down the breathing and heartbeat.
