Theory and practice in the description of the Object to be taken to the Bath Description of the object to be taken to the Bath 226 warmth ( chemical reactions that form warmth take place simultaneously in all cells, even in the brain ones, these cells warm not only the external ambience, but also the bones). Some of the warmth leaves the body with exhaled air, some with excrement and urine, but approximately 90% of the total warmth loss is through the skin (if we calculate the warmth released with the excrement, we get a medium-power atomic bomb). When the external temperature is low, the temperature-sensitive nerve endings in the skin become irritated, and the skin capillaries become narrower reflexively, thereby reducing the flow of blood through the skin (one of the causes of myocardial infarction) and reducing warmth loss (the Brain does not suspect it) . In the warm ambience, the opposite happens: the capillaries get wider, the skin turns pink as a result of the increased blood flow and gives off a lot of warmth (according to this conclusion, under normal conditions, the skin has an average color of the spectrum, that is, green). At a very high ambient temperature, this mechanism can not ensure the return of the necessary warmth, so the sweat glands in the skin emit unusually much of sweat (the cells, of course, do not know who and why takes away the sweat). Evaporation of sweat from the skin surface lowers the body temperature, taking away from the body the heat necessary to convert the sweat into water vapor; to convert 1 liter of water into vapor, 540,000 calories are required (if a pot of water is put on fire, the resulting vapor cools the water – as a method of getting ice). In the skin there is a number of different sensitive receptors, through which we can feel pressure, temperature and pain and are able to distinguish various objects that we touch. The receptors respond to the following stimuli: Krauze's endinds – to cold, Ruffini's papillary endings – to warmth, Meissner's corpuscles and Merkel's discs – to touch, Pacini's corpuscles – to heavier pressure, free nerve endings – to pain stimuli (the skin does not have receptors for analyzing the composition of gases , radiation, alkalinity and acidity – these analyzes are carried out in closed laboratories of the internal organs by absorbing external stimuli). There are specialized glands in the skin: about 2.5 millions sweat glands are scattered all over the body (many are lying unattended), but
