baroreceptor

Baroreceptors are specialized sensors located in your blood vessels, mainly in the carotid arteries and aorta. They continuously monitor blood pressure by detecting stretch or pressure changes in the vessel walls. When blood pressure rises, baroreceptors send signals to the brain to lower it, typically by slowing the heart rate and dilating blood vessels. Conversely, if blood pressure drops, they signal to increase it. This rapid feedback mechanism helps maintain stable blood pressure levels, ensuring that your organs receive a consistent blood supply. In essence, baroreceptors act as your body's immediate blood pressure regulators.
