Responses of ACTH, epinephrine, norepinephrine,... [Am J Physiol. 1986. Polezni/blood loss.pdf. Baroreflex. The baroreflex or baroreceptor reflex is one of the body's homeostatic mechanisms which helps to maintain blood pressure at nearly constant levels.
The baroreflex provides a rapid negative feedback loop in which an elevated blood pressure reflexively causes the heart rate to decrease and also causing blood pressure to decrease. Decreased blood pressure decreases baroreflex activation and causes heart rate to increase and to restore blood pressure levels. The baroreflex can begin to act in less than the duration of a cardiac cycle (fractions of a second) and thus baroreflex adjustments are key factors in dealing with postural hypotension, the tendency for blood pressure to decrease on standing due to gravity.
