Why do people write?
It is known that the body of the averageA person is 80% water. All life processes of living systems - from bacteria to highly organized organisms, can only take place in an aqueous medium, since it is a universal solvent. An organism is a dynamic system that needs constant replenishment of energy to carry out its work. Nutrients come from outside, participate in metabolism, formed in the process of this "waste", i.e. products of disintegration, are output through special excretory systems. They are toxic and, accumulating, can cause the death of the body. According to the laws of physics and biochemistry, they can be excreted only in the form dissolved in water. The final product of protein metabolism is the toxic compounds - urea and ammonia, which are excreted in the urine.
Here lies the answer to the question why peoplewrite. In fact, this is a vital process. It turns out that people should drink, so that they have something to write about! We are thirsty, because our body thus signals that there is not enough water in the body to metabolize.
For a day in the human body comes about 2500ml of water. To maintain a constant amount of water, its intake must correspond to excretion. The main role in this is played by the kidneys. The daily urination is an average of 1500 ml, the rest of the water is excreted by the lungs, the skin and with the feces.
In the tissues of the kidneys coming from the bloodstreamthe liquid is filtered from the decay products of proteins, purines, harmful chemical compounds and concentrated. Then the formed urine accumulates in the bladder, then it goes to the outlet through the urethra. These processes at all stages are regulated by the nervous and hormonal system. Therefore it is understandable why people write regularly.
