What is "antidiuretic hormone"?

Antidiuretic hormone (ADH), also known as vasopressin, is an important hormone of the endocrine system. It is produced by the hypothalamus and released by the pituitary gland. ADH plays a crucial role in regulating water balance and maintaining proper fluid levels in the body. It acts on the kidneys to decrease urine production and increase water reabsorption, thereby conserving water and preventing excessive fluid loss. ADH also has vasoconstrictive effects, helping to regulate blood pressure. Overall, ADH helps to maintain body fluid homeostasis and ensure proper hydration.
