When the adh is released what happens?

When antidiuretic hormone (ADH), also known as vasopressin, is released, it primarily promotes water reabsorption in the kidneys. This hormone acts on the collecting ducts, making them more permeable to water, which helps concentrate urine and conserve body water. As a result, blood volume and blood pressure may increase, while urine output decreases. Additionally, ADH can cause blood vessels to constrict, further influencing blood pressure.
