Question

Quizplus · Accepted Answer

ADH is released in response to increased osmolality and decreased volume of intravascular fluid; it promotes water retention in the renal system by increasing the permeability of renal tubules to water.Renin release is stimulated by diminished blood flow to the kidneys.Aldosterone is secreted by the adrenal cortex.It enhances sodium reabsorption in renal tubules,promoting osmotic reabsorption of water.Renin reacts with a plasma globulin to generate angiotensin,which is a powerful vasoconstrictor.Angiotensin also stimulates the release of aldosterone.
