Detailed explanation-1: -Antidiuretic hormone is made by a part of the brain called the hypothalamus and is secreted into the blood by the pituitary gland. Certain types of tumors may release high amounts of antidiuretic hormone, which can cause low levels of sodium in the blood and the body to retain water.

Detailed explanation-2: -The posterior lobe of the pituitary gland stores and releases (secretes) only two hormones: Antidiuretic hormone (ADH, or vasopressin): ADH helps regulate the water balance in your body by controlling the amount of water your kidneys reabsorb while they’re filtering wastes out of your blood.

Detailed explanation-3: -ADH, also called vasopressin, is synthesized by the neurons in the hypothalamus and stored in the posterior pituitary until released upon neural stimulation.

Detailed explanation-4: -The synthesis of ADH occurs in the supraoptic and paraventricular nuclei in the hypothalamus. It is then transported to the posterior pituitary gland via the neurohypophysial capillaries.
