We developed a method to calculate entropy values associated with mutual diffusion of substances and to articulate an exergy-entropy process of human body in terms of water and other inorganic substances. The purpose is to have a better understanding of the consumption process of freshwater resource of human body. It was found that human body consumes 95% of the supplied exergy of inorganic matter and disposes of the rest, namely 5%, with urine. The amount of water, 1.0〜1.6kg/day, which is required by human body, was confirmed to be optimum for maintaining actively the state of exergy in terms of inorganic matters in human body, while consuming the least exergy of freshwater. The disposal of entropy generated within human body by urination makes room for consuming exergy contained by freshwater.
