Summary

Body water is contained in intracellular and extracellular compartments, in approximately a 2:1 ratio. The ionic concentrations are quite different between compartments and Na+, and the predominant cation in the ECF, Na+, is of particular significance with respect to maintaining the volume of the ECF. Several specialized organs and hormones for maintaining ionic and fluid balance are described.
