sinoaortic baroreceptors

Sinoaortic baroreceptors are specialized nerve sensors located in the aorta and carotid arteries that detect changes in blood pressure. When blood pressure rises, these sensors send signals to the brain to reduce heart rate and dilate blood vessels, lowering pressure. Conversely, if blood pressure drops, they signal the brain to increase heart rate and constrict vessels, raising pressure. This feedback system helps maintain stable blood pressure levels, ensuring organs receive a consistent blood supply. Essentially, sinoaortic baroreceptors act as the body's pressure monitors, helping keep blood pressure within healthy ranges.
