During the life of the body it occurs, on the one hand, the destruction (dissimilation) substances included in the composition of tissues and cells, on the other — a constant renewal, restoration and rebuilding previously destroyed substances due to the nutrients supplied from food (assimilation) . These two processes that make up metabolism are closely linked, are in interdependence and a state of dynamic equilibrium, with the result that cells and tissues retain their relatively constant composition. With the destruction of substances in the body the oxidation of complex organic substances in the composition and allocation of this energy needed for muscle work the body, keeping at a certain level of body temperature and other vital processes. The same energy, released during the destruction, is necessary to ensure the processes of reconstruction, during which there is a formation of simple organic compounds complex, with a large reserve of energy. This process is called metabolism in the body. It is the basis of all physiological functions of the body, which include breathing, blood circulation, digestion, nervous activity, etc.All these manifestations of the body are under the regulatory influence of the nervous system.
Now mobile phones are at all. Naturally, because it allows us to be in touch with loved ones at any time. I remember when there were no mobile phones, it was difficult to catch someone's home, calling on the city. A call to another city, people went to the post office and ordered negotiations. Now everything is different. Parents can call the child to walk on the street and make sure he's all right. You can be in touch with old grandparents and time to come to their aid, if you suddenly need. You can prevent the person with whom you go to a meeting, if delayed or can not come. Thanks to the mobile phone it is possible at any time to contact with the right person. And this is a very big plus mobile phone, which has become very popular and accessible to all.
I believe that mobile telephony - is unconditional achievement of technology, which is a person in all spheres of life. The fact that some people manage to use mobile phones not only benefit, but harm - it is their personal choice that depends on their level of culture and understanding, and this is a separate topic for reflection.
