baroreceptorrefleksen
Baroreceptor reflex, also known as the baroreflex, is a physiological mechanism that helps regulate blood pressure and heart rate. It is a negative feedback loop that monitors the pressure within the blood vessels and adjusts the cardiovascular system accordingly. The baroreceptors are specialized sensory receptors located in the walls of the carotid sinus and aortic arch, which are sensitive to changes in blood pressure.
When blood pressure increases, the baroreceptors stretch, sending signals to the brainstem via the glossopharyngeal and
Conversely, when blood pressure decreases, the baroreceptors are less stretched, leading to a decrease in the
The baroreceptor reflex is crucial for maintaining homeostasis, as it ensures that the body can respond to
