A)A drop in renal perfusion stimulates renin release. Renin converts angiotensinogen to angiotensin I, which is then converted to angiotensin II in the lungs. Angiotensin II is a vasoconstrictor and also promotes sodium and water retention, raising blood pressure. Catecholamines, ANP, BNP, and adrenomedullin do help regulate blood pressure, but they are not released from the kidneys.
