Final answer:
ADH exerts a vasopressor effect while BNP and ANP have the opposite effect of promoting vasodilation and diuresis.
Step-by-step explanation:
ADH (Antidiuretic hormone) exerts a vasopressor effect. ADH is released by the posterior pituitary gland in response to low blood volume or increased blood osmolality, stimulating water reabsorption in the kidneys and causing vasoconstriction in blood vessels.
BNP (Brain natriuretic peptide) and ANP (Atrial natriuretic peptide) actually have the opposite effect. They are released by the heart in response to increased blood volume and pressure. BNP and ANP promote diuresis and vasodilation, helping to decrease blood volume and pressure.
