<P> About two thirds of the total body water of humans is held in the cells , mostly in the cytosol , and the remainder is found in the extracellular compartment . The extracellular fluids may be divided into three types : interstitial fluid in the `` interstitial compartment '' ( surrounding tissue cells and bathing them in a solution of nutrients and other chemicals ) , blood plasma and lymph in the `` intravascular compartment '' ( inside the blood vessels and lymphatic vessels ) , and small amounts of transcellular fluid such as ocular and cerebrospinal fluids in the `` transcellular compartment '' . The interstitial and intravascular compartments readily exchange water and solutes but the third extracellular compartment , the transcellular , is thought of as separate from the other two and not in dynamic equilibrium with them . </P>
what are the two extracellular fluid compartments in the body
