Water is the most important making element for all live. It is considered that it is much more necessary for the person, than, for example, food, in a human body liquid occupies 70-75% of all body weight.
Instruction
1. One of properties of water - the universal ability to dissolve chemicals thanks to what it keeps elasticity of a biological cage, feeds it and participates in creation of a membrane. All internal "juice" of the person – blood and a lymph; sekretorny liquid – saliva, bile, gastric juice; allocations from genitals, urine, sweat – all this water solutions with special substances.
2. The molecule of water has a neutral electronic charge, it consists of compound of atoms of oxygen and hydrogen. The electronic charge in the molecule is distributed very unevenly: in the field of hydrogen atoms with a positive electronic charge prevail, and in arrangement of oxygen - with negative. It is a dipole, and it, as we know, has good ability to unite in connections with other substances and to form hydrates. When energy of an attraction of water to molecules of other substance is higher, than between water molecules, substance in it is just dissolved.
3. Concentration of water in biological liquids defines speed of interaction of substances. There are internal processes quicker: products of disintegration of biochemical reactions are removed, processes of restoration and updating of an organism become more active. At dissolution of substance of its molecule by means of water have an opportunity to move quicker why its reactionary ability increases. At decrease in content of water in an organism blood becomes "knitting", moves on veins and vessels more slowly, the metabolism slows down, the general condition of the person begins to worsen quickly, the brain which consists for 85% of liquid begins to suffer.
4. At dehydration of an organism of the first cellular liquid suffers, it decreases up to 66%, then extracellular and only later the amount of liquid in blood plasma is reduced. The nature arranged so that providing principal organ of activity – a brain, is conducted to the last. Big loss of liquid at the person is capable to lead to irreversible consequences, cases not only death of people from dehydration, but also approaches at them heavy illnesses are known to medicine, in particular, from a lack of water and also from its surplus the schizophrenia developed, patients quickly went crazy.
5. Thanks to water thermal capacity, its participation in regulation of body temperature plays an important role, thermoregulation processes are carried out, temperature of cages, optimum for biological activity, is maintained in an organism. Transportation of nutrients and oxygen accelerates.
6. Water also takes part in process of digestion and removal of products of processing of an organism. It stimulates to work of a wall of intestines, it dissolves processing products, removing them on mochetoka.
7. It is curious that water, in fact, and the major protective factor for internals of the person. For example, the liver, kidneys, a spleen have very considerable specific weight, at physical activity theoretically they have to just come off, the carrying-out channels and the holding sheaves are very thin. Saves them from it liquid in which they as if swim. Liquid extinguishes blows, creates a biological environment, changes their physical weight, leading to minimum (Archimedes's law in operation).
