5. Both osmoreceptors and baroreceptors stimulate the release of antidiuretic hormone (ADH) from the pituitary gland. ADH signals the kidneys to reduce urine production and initiates a sequence leading to increased production of angiotensin II.

Angiotensin II constricts blood vessels to maintain blood pressure and triggers the release of aldosterone. Aldosterone signals the kidneys to retain sodium. (LO3)
