	Definition:		ECF is the abbreviation often used to indicate extracellular fluid. It is the volume of body fluid exclusive of that in the cells (intracellular fluid, ICF). Therefore ECF includes fluid in the blood vessels, and in the interstitial space (the space between cells). About 20 percent of body weight is ECF: 5 percent is plasma, and 15 percent is interstitial fluid.
