Water is the single biggest ingredient of human body. The weight of water in the body of an individual as a percentage of total body weight can vary from 45% to 75%. On average adult male body contains about 60% water by weight. This figure is 55% for females.

Percentage of water in some of the parts of the body are as follows:

Lean muscle tissues : 75%

Blood                       : 95%

Fat                          : 14%

Bones                     :22%

The total body water can be divided in two categories:

  • Intracellular Fluid: This constitutes about two thirds of total body water.
  • Extracellular Fluid: This constitutes about one third of total body water.
