Following principles are put in a basis of classification of receptors: Evaporation is a return of heat in environment at the expense of evaporation of sweat or a moisture from a surface of a skin and mucous respiratory ways. At environment temperature nearby 20°С evaporation makes nearby 36 г/ч. 0,58 kcal of thermal energy are spent For evaporation 1 г waters, i.e. by evaporation the human body gives in these conditions about 20 % of all disseminated heat. Increase of external temperature, physical activity performance strengthen потоотделение, and it can increase to 500 - 2000 г/ч. If the external temperature exceeds average value of temperature of a skin the organism cannot give to environment warmly radiation, конвекцией and теплопроведением, therefore strengthening of evaporation of a moisture from a body surface becomes unique way of dispersion of heat. Such evaporation is possible until humidity of air of environment remains less than 100 %. At intensive потоотделении, high humidity and small speed of movement of air of a droplet of sweat, without having time to evaporate, flow down from a body surface, теплоотдача by evaporation becomes less effective. On 1 см2тыльной at the inhabitants living in a midland of Russia, it is necessary a surface of a hand 11 - 13 холодовых and 1 - 2 thermal receptors. At холодовых receptors the constant импульсация is observed in a range from 41 to 10°С, and optimum sensitivity - in limits from 15 to 30°С. Thermal receptors react constant frequency ПД in a range from 20 to 50°С with optimum sensitivity within 34 - 42°С. It is static reaction of receptors. Temperature changes on 0,2°С cause changes импульсации receptors towards its reduction or increase. Such reaction of thermoreceptors is called as dynamic. Viagra for sale in england
