Exchange of water and salts depends on The size of gradient Surface area of the animal

Cell plasma membrane maintains ionic , but not osmotic difference between intracellular and extracellular fluids. Epithelium surrounding the body often maintains both ionic and osmotic difference between animal and their environments.
