What is the function of Vasopressin (anti-diuretic hormone) when thirst signals are active?
Answer
It instructs the kidneys to retain more water, reducing output.
When the body detects increased blood concentration indicating dehydration, a dual action is initiated to restore equilibrium. Alongside triggering the sensation of thirst to promote water intake, the body releases the anti-diuretic hormone, often referred to as vasopressin. This hormone acts directly on the kidneys, signaling them to conserve the remaining body water by retaining it rather than excreting it as urine. This dual response—encouraging intake via thirst and minimizing output via ADH—is essential for fighting fluid imbalance.
