The Major Hormone That Regulates Water Loss Is

Question

The major hormone that regulates water loss is
A)ANP
B)Angiotensin II
C)Renin
D)ADH
E)Angiotensin

Accepted Answer

ADH (antidiuretic hormone), also known as vasopressin, is the major hormone that regulates water loss in the body. It is produced in the hypothalamus and released from the pituitary gland in response to changes in blood volume or blood osmolality. ADH acts on the kidneys to increase water reabsorption, which reduces water loss in urine and helps maintain water balance in the body. The other hormones listed (ANP, Angiotensin II, Renin, and Angiotensin) are involved in the regulation of blood pressure and electrolyte balance, but not the primary regulators of water loss.
