ANATOMY

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.

Detailed explanation-2: -ADH is a substance produced naturally in an area of the brain called the hypothalamus. It is then released by the pituitary gland at the base of the brain.

Detailed explanation-3: -Antidiuretic hormone (ADH), also known as vasopressin, is a small peptide hormone which regulates the body’s retention of water. It is one of only two hormones secreted by the posterior pituitary gland.

Detailed explanation-4: -The hormones produced by the posterior pituitary gland include vasopressin and oxytocin. Vasopressin is also referred to as antidiuretic hormone (ADH) and acts on the kidney to conserve water. It is also important for maintaining fluid and electrolyte balance in the body.

Detailed explanation-5: -Hyperosmolar states most strongly trigger its release. ADH is stored in neurons within the hypothalamus. These neurons express osmoreceptors that are exquisitely responsive to blood osmolarity and respond to changes as little as two mOsm/L. [2] Therefore, slight elevations in osmolarity result in the secretion of ADH.
