What is the purpose of Antidiuretic hormone (ADH)?
The Antidiuretic Hormone regulates the body's ability to retain water.
The kidneys are wired to automatically expel the urine stored in the bladder which is collected from the filtered blood. However, if there is no ADH, the kidneys will continue to expel water from the body even if it is not yet full. Think of it as a faucet that got the valve broken.
