Much the same way that a regular kidney does. Your kidneys work essentially by a salt imbalance... one half of your kidney has a higher salt content than the other.As the blood moves through the kidney, the salt absorbs the liquid.Waste is channeled to the ureter towards the bladder, while other liquid is returned to the blood.
