An increase in serum osmolality would be expected to ________ secretion.
A) increase vasopressin
B) decrease vasopressin
C) decrease ADH
D) decrease aldosterone

Question

Quizplus · Accepted Answer

An increase in serum osmolality stimulates the release of vasopressin,also referred to as antidiuretic hormone.Tubular epithelial cells allow free diffusion of water from the tubular fluid into the cell.The enhanced reabsorption conserves water in the body,creates concentrated urine,and reduces serum osmolality.ADH secretion is stimulated by baroreceptors in response to hypovolemia.When body fluids become too concentrated,ADH is released.Aldosterone is not decreased in response to serum osmolality.
