When baroreceptors sense a drop in blood pressure, the vasomotor center responds by triggering peripheral vasoconstriction. When there is decreased blood pressure thei baroreceptor firing decreases, thus decreasing the activity of cardiac inhibitor centers, and increasing the activity of accelerator centers and the vasomotor center, therefore this results to an increased cardiac output and an increased vasoconstriction which results to increases blood pressure back to normal.
