Quizplus · Accepted Answer

Baroreceptors are specialized sensory receptors located in the walls of blood vessels, particularly in the carotid sinuses and the aortic arch. They detect changes in blood pressure and send signals to the brain to initiate responses to maintain blood pressure within normal limits, making them a key component of the body's internal process to regulate blood pressure.
