The first anti-diuretic (water retention) hormone within the physique. The posterior pituitary gland secretes it in response to nerve alerts obtained from superior mind sensors that detect delicate adjustments in water steadiness. Circumventricular organs are the identify for these advanced sensors.

The kidneys will make molecular changes to each underhydration and overhydration inside 40 seconds in response to any upset within the water steadiness. These changes end result from the mobilization armies of AQP-2 water channels, numbering about 12 million per gathering duct cell.

Because of this once we drink extra water than our physique wants {8 cups of water} – above thirst – we instantly should pee out any extra water.
