Water

Basics:

Water is the main and indispensable component of the human body. Human beings can not be without drinking more than five or six days without endangering his life. The human body is 75% water at birth and about 60% in adulthood. Approximately 60% of this water is in the interior of the cells (intracellular water). The rest (extracellular water) is flowing in the blood and bathes the tissues.

In combustion reactions occurring nutrients inside cells produce energy for small amounts of water. This formation of water is greater by oxidizing fats - 1 gr. of water per gr. fat - that starches -0.6 gr. per g. of starch. The water produced in cellular respiration is called metabolic water, and is essential for animals adapted to desert conditions. If camels can withstand months without drinking is because they use the water produced by burning stored fat in their humps. In humans, the production of metabolic water with a normal diet is as little as 0.3 liters per day.

As shown in the following figure, the body loses water through different channels. This water has to be recovered by offsetting losses with intake and avoiding dehydration.
