<P> Body fluid , bodily fluids , or biofluids are liquids within the bodies of living people . In normal healthy men , the total body water is about 60 % of the total body weight ; it is slightly lower in women . A 70 kg ( 160 pound ) man , then , has 42 liters of water in his body . This is divided between ICF and ECF in a two - to - one ratio : 28 liters are inside cells and 14 liters are outside cells . This ECF compartment is divided into the fluid between cells - the interstitial fluid volume - and the vascular volume , also called the blood plasma volume . The vascular volume is divided into the venous volume and the arterial volume ; and the arterial volume has a conceptually useful but unmeasurable subcompartment called the effective arterial blood volume </P>
