人体由神经、骨骼、肌肉、筋膜、脂肪、内脏,皮肤等所组成,无论其胖瘦和高矮如何,他的体重的70%是水,这水是和蛋白质及无机监类(纳、钾、钙、镁)形成溶液,即所谓体液,而存在于体内的。所有体液都分布在细胞内和细胞外两大间隔内,细胞外间隔又分为组织间(即细胞间)和血管内(见附图)两部分。细胞内的体液量最大,约为体重的50%;细胞外的体液则仅占体重的20%,其中5%在血管内,15%在组织间。血管内的体液称为血浆,它的量虽小,但所起的作用最大,因为它是心脏和血管的内容物。如果它的量有增减,直接可以影响心脏和血管的机能,间接可以影响全身其它脏器。人体的正常生理作用祗有在体液平衡的状
The human body consists of nerves, bones, muscles, fascia, fat, viscera, skin and so on, regardless of their weight and height and height, 70% of his body weight is water, which is water and protein and inorganic monitoring class , Calcium, magnesium) to form a solution, the so-called body fluid, which exists in the body. All body fluids are distributed in the cell and the extracellular space, the extracellular space is divided into inter-organizational (ie, intercellular) and intravascular (see photo) in two parts. The largest amount of fluid in the cells, about 50% of body weight; extracellular fluid only accounts for 20% of body weight, of which 5% in the blood vessels, 15% in the tissue. Vaso-fluid, known as plasma, is small in quantity but has the greatest effect because it is the heart and blood vessel contents. If it increases or decreases in quantity, it can directly affect the function of the heart and blood vessels and indirectly affect other organs in the body. The body’s normal physiological role only in the shape of fluid balance
