AB Total  body  water  (TBW)  constitutes  50%–75%  of  the  total  body  mass,  depending  on  age,  sex,  and  fat  content.  After  an  initial  brisk  postnatal  diuresis,  the  TBW  slowly  decreases  to  the  adult  range  near  puberty.  TBW  is  divided  into  the  intracellular  and  extracellular  spaces.  Intracellular  fluid  (ICF)  accounts  for  two-thirds  of  the  TBW  and  extracellular  fluid  (ECF)  for  one-third.  The  ECF  is  further  compartmentalized  into  plasma  (intravascular)  volume  and  interstitial  fluid  (ISF).
