Comments "In mammals and other multicellular animals, about 60% of the body mass is water, which is distributed between two major fluid compartments (Fig. 2): the extracellular compartment (~20% of the body mass), the environment in which the body cells live, which is divided into the intravascular fluid compartment or plasma (~5% of the body mass) and interstitial fluid (~15% of the body mass) and the intracellular compartment (~40% of the body mass)."
