1-5.Classification and action of perspiration
	Classification ●The sweat is from a sweat gland to an indispensable action on perspiration for secretion and the temperature maintenance.
	＜Sensible perspiration＞ When the temperature rises when the temperature rises or does sports, it sweats, and the sweat secreted on the surface of the skin evaporates, the temperature is kept constant depriving of heat of vaporization. The perspiration felt to sweat like this is said, "Sensible perspiration".
	＜No sensible perspiration＞ "No sensible perspiration" that becomes steam that doesn't understand with the unassisted eye and transpires is a sweat that always evaporates constantly from the skin regardless of the temperature adjustment at the rest. The amount of perspiration during a day is from about 1 to 1.5 liters it, and the amounts equal to the urinary output during a day. There is an action that exhausts body wastes in the sweat, too.
	Element of sweat ●The sweat is scentless and a limpid liquid. 99% is water, and the remainder 1% contains sodium chloride, the urea, the uric acid, the lactic acid, fat, and the amino acid, etc.It gradually inclines at alkalescence if staying long on the surface of the skin though the pH value is acidulous from 3.8 to 5.6.
	＜Eccrine gland＞ It exists in most parts of the entire body. It has it from two million to three million eccrine glands though the number depends on the individual variation and the climate climate on the migration ground. Rising prevention of the temperature and the sebum membrane are formed.
	＜Apocrine sweat glands＞ It is in the limited part like the armpit and the anus surroundings, etc.The amount of the secretion of the sweat is few, and irrelevant to the temperature adjustment. It transmits to the follicle of hair in the open mouth hair and it secretes it in the epidermal.
	�@Transpiring of water by secretion of sweat �AIt is absorbed from the depths of the epidermal to the sweat duct and it transpires from the sweat entrance. �BIt is absorbed from the sweat duct in stratum corneum to the corneum layer and it transpires. �CThe water discharged by the process of keratinization of the epidermal transpires. �DThe body fluid supplied by the capillary transpires.
