Normal circulatory homeostasis depends upon there being a level of basal activity of both the sympathetic and parasympathetic nervous systems - the balance of the ANS is governed by the medulla oblongata in cardioinhibitory and vasomotor centres. The ANS is the most rapidly responding regulator of blood pressure.
