What is antidiuretic hormone?
It is also called human vasopressin. It is synthesized by special nerve cells present in the hypothalamus. It is then transported to the posterior pituitary gland and from there it is released into the blood.
This hormone acts on the kidneys and the blood vessels. It helps in controlling and maintaining the normal blood pressure of the body. It works by maintaining the fluid volume in the body by keeping a check on the water that is passed out through urine.
This is done by reabsorption of some amount of water from the urine through a designated area in the kidney.
