Elevations in the circulating levels of vasopressin within the physiological range (less than 30 fmol X mL-1) in conscious animals cause vasoconstriction of resistance vessels, the most profound effect occurring in the muscle, skin, and intestinal vascular beds. In the organism with normal baroreceptor function, the vasoconstriction is not expressed as an increase in arterial pressure because of a corresponding fall in cardiac output associated with enhanced cardiovascular reflex activity.
