Quizplus · Accepted Answer

Aldosterone is the primary hormone that regulates sodium levels in the body. It acts on the kidneys to increase reabsorption of sodium back into the bloodstream, thereby reducing sodium excretion in urine. ADH (A) primarily regulates water balance, while glucocorticoids (D) have a secondary effect on sodium retention. Water levels (C) can indirectly affect sodium levels by altering the concentration of electrolytes in the body, but it is not a primary controller.
