Considering the negative feedback system for the control of blood pressure, when a blood pressure rise is noted in the arterial receptors, what is the expected response?
A) Arterial vasoconstriction
B) Decreased inotropic state
C) Increased heart rate
D) Venoconstriction

In the case of the arterial receptors, a rise in blood pressure increases aortic and carotid receptor stretch, and thus the discharge rate. The increased discharge rate causes an opposite response by the medullary centers (i.e., a depressor response). Venomotor tone decreases, blood vessels dilate, and heart rate and contractility both decrease.
