[A] : The hormone aldosterone is secreted by adrenal cortex after the low `Na^+` content in blood and the resultant low BP causes the kidney to release renin.   [R]: Renin in blood leads to the formation of angiotensin II which causes adrenel cortex to release aldosterone that causes kidney to re- tain `Na^+` and, therefore, water is reabsorbed and BP rises.
