Which of the following regulatory mechanisms would be stimulated as a result of the increased osmolality that results from a Na+ level of 152 mEq/L?

B)an increased release of ADH
C)an increase in renin production
D)an increase in the secretion of aldosterone
E)a decreased release of ADH

When the osmolality increases, the body responds by releasing more antidiuretic hormone (ADH) from the posterior pituitary gland. ADH increases water reabsorption in the kidneys, leading to less urine output and a decrease in osmolality. Therefore, choice B (an increased release of ADH) would be stimulated in response to the increased osmolality caused by a high Na+ level.
