Explain the function of baroreceptor reflexes
What will be an ideal response?
Baroreceptor reflexes respond to changes in blood pressure. The baroreceptors — located in the walls of the carotid sinuses and aortic arch — monitor the degree of stretch at those sites. When blood pressure increases, the cardiac centers decrease cardiac output and the vasomotor center is inhibited, resulting in vasodilation; when blood pressure decreases, the cardiac centers increase cardiac output and the vasomotor center is stimulated, resulting in vasoconstriction.
