Which of the Following Hormones Causes Water Retention by the Kidneys

Question

Which of the following hormones causes water retention by the kidneys in times of dehydration?
A)Glucagon
B)ADH
C)Somatostatin
D)PTH
E)Adrenal androgens

Accepted Answer

ADH (antidiuretic hormone), also known as vasopressin, is released by the pituitary gland in response to dehydration. Its main function is to increase the permeability of the kidneys to water, allowing for increased water reabsorption and retention in the body. This helps to prevent further dehydration and maintain fluid balance.
