An increase in plasma osmolality leads to increased action potentials to the supraoptic region of the hypothalamus, which results in increased secretion of vasopressin (antidiuretic hormone) from the posterior pituitary gland. Vasopressin acts on the kidneys to increase water reabsorption and reduce urine output, helping to dilute the plasma back to normal osmolality.
