Explanation:
Detailed explanation-1: -The current consensus is that arterial baroreceptors are vitally important in the short term (seconds to minutes) control of mean arterial pressure (MAP) but are unimportant in determining the long-term level of MAP.
Detailed explanation-2: -The short-term regulation of blood pressure is managed through the baroreceptors in the carotid artery and aortic arch.
Detailed explanation-3: -Arterial baroreceptors control the sympathetic drive to the heart and the peripheral blood vessels. They constantly adjust the sympathetic activity in relation to systemic blood pressure changes in order to maintain homeostasis.
