Epinephrine, released by the adrenal medulla, triggers vasoconstriction in response to a drop in blood pressure, which helps raise blood pressure back to normal levels. Aldosterone conserves water by increasing renal absorption of sodium and potassium ions, and does not have an immediate effect on blood pressure. Cortisol and insulin have important roles in metabolism and energy regulation, but do not play a significant role in the immediate response to low blood pressure.
