Antidiuretic hormone (ADH) is also known by which name?

Explanation:
ADH is also known as vasopressin. It is produced in the hypothalamus and released from the posterior pituitary, with the main job of conserving body water by acting on the kidney’s collecting ducts to insert aquaporin-2 channels. This promotes water reabsorption, concentrates the urine, and reduces urine volume. The name vasopressin highlights its ability to cause vasoconstriction at higher concentrations, but physiologically its primary role is water balance. The other substances listed have different endocrine or enzymatic roles: oxytocin mediates uterine contractions and milk ejection; prolactin stimulates milk production; renin is an enzyme in the RAAS pathway.
