CORRECT Answers
aldosterone is influenced by what? - CORRECT ANSWER - circulating blood volume,
blood pressure, plasma concentrations of sodium and potassium
what is released when circulating blood volume of BP is decreased or sodium is decreased or
potassium is increased? - CORRECT ANSWER - renin is secreted and released by the
kidneys
renin stimulates the release of what? - CORRECT ANSWER - angiotensin
