Total body water (TBW) is the sum of the intracellular and extracellular compartments. In a 70-kg adult male, it comprises 60% of body weight or about 42 L. This value can vary with age, gender, and with the amount of adipose tissue versus lean muscle present in the body, as the latter has higher water content.
