what is osmoregulation ?

Osmoregulation is the process of maintaining of an optimal, constant osmotic pressure in the body of a living organism.

 Osmoregulation is important to organisms to keep a constant, optimal osmotic pressurewithin the body or cell . It is the way by which an organism maintains suitableconcentration of solutes and amount of water in the body fluids . An example employed by organisms is excretion (such as getting rid of metabolic wastes and other substancestoxic to the body when they are in large amounts).
