WebADH has two major effects. It constricts the arterioles in the peripheral circulation, which reduces the flow of blood to the extremities and thereby increases the blood supply to the core of the body. WebWhen it gets a signal from angiotensin 2, it'll start sending off its own hormone called ADH. And ADH is antidiuretic hormone. It'll definitely cause vasoconstriction of the blood vessels, just like angiotensin 2 did. But instead of that sodium reabsorption, this ADH actually causes water reabsorption.

Dehydration or physiological stress can cause an increase of osmolarity above 300 mOsm/L, which in turn, raises ADH secretion and water will be retained, causing an increase in blood pressure.

WebVasopressin (arginine vasopressin, AVP; antidiuretic hormone, ADH) is a peptide hormone formed in the hypothalamus, then transported via axons to the posterior pituitary, which releases it into the blood.
