ANATOMY

Detailed explanation-1: -The hypothalamus produces a polypeptide hormone known as antidiuretic hormone (ADH), which is transported to and released from the posterior pituitary gland. The principal action of ADH is to regulate the amount of water excreted by the kidneys.

Detailed explanation-2: -ADH then acts primarily in the kidneys to increase water reabsorption, thus returning the osmolarity to baseline.

Detailed explanation-3: -A hormone that helps blood vessels constrict and helps the kidneys control the amount of water and salt in the body. This helps control blood pressure and the amount of urine that is made.

Detailed explanation-4: -Water absorption in the kidney is controlled by the hormone vasopressin which is a peptide very similar in structure to oxytocin (cf. Chapter 17). Vasopressin causes greatly enhanced water absorption by the kidney and is sometimes known as the ‘antidiuretic hormone’ (ADH).

Detailed explanation-5: -It is also called as the Vasopressin. It is naturally occurring hormone which helps in controlling various physical processes & several life-threatening conditions, including bleeding abnormalities and septic shocks. The low level of Antidiuretic hormone in blood cells results in: Diabetes insipidus.
