Through the transport of dissolved substances and the entrainment of materials, water participates in geological processes and in the body’s circulation of nutrients and waste. Water in the biosphere transports matter and energy, supports the development of life, is an essential and major component of living matter and is part of inert matter in varying proportions. These constitute a means in which natural resources undergo the physical, chemical and biological processes that govern their physical evolution. Surface waters are an essential component of the water cycle in the troposphere. Only 0.7% of the Earth’s water is fresh, in the form of lakes, rivers, aquifers and steam. About 7% of the Earth’s mass is water, of which 97% is salt water and a large part of the remaining 3% is in the form of ice. The Earth and the atmosphere that surrounds it contain large amounts of water. In short, water is not only the important life support we know, but it is a basic element for Its survival and development. Our body uses water as a means of transport and storage of nutritional substances, or as a means of evacuation of the elements to be eliminated.-In order to maintain the appropriate level of water, a person has to return to his body about two liters of water daily, which are lost through urine, breathing, perspiration, sweat and fecal matter. It is responsible for maintaining the temperature of the human body by lowering it by perspiration of the skin, sweat, to compensate for a high outside temperature or the excess heat produced by our body.
