The extracellular fluid [extra-, outside of] is the watery internal environment of multicellular organisms. Extracellular fluid surrounds the cells and acts as a transition between an organism's external environment and the environment inside their cells[1], the intracellular fluid. Because of this, the extracellular fluid must maintain relatively stable conditions, for example pH and concentrations of water, ions and glucose. These conditions are regulated by the mechanism of homeostasis.
