A
To stimulate the release of insulin from the pancreas
B
To increase water reabsorption in the kidneys
C
To promote the breakdown of glycogen in the liver
D
To regulate calcium levels in the blood
Verified step by step guidance1
Understand that antidiuretic hormone (ADH), also known as vasopressin, is a hormone produced by the hypothalamus and stored in the posterior pituitary gland.
Recognize that the primary function of ADH is related to the regulation of water balance in the body.
ADH acts on the kidneys, specifically targeting the collecting ducts, to increase their permeability to water.
This increased permeability allows more water to be reabsorbed from the filtrate back into the bloodstream, reducing urine volume and concentrating the urine.
By increasing water reabsorption, ADH helps maintain blood pressure and proper hydration levels in the body.
