水是人体不可缺少的主要成分,也是卫生保健、防病治病的良药。譬如因病1-数周不进食物,但只要饮水其生命可维持下去,如不饮水,连一周也难以生存。人体内的血液、淋巴液、各种分泌液、消化液、唾液、泪水、汗、尿等都离不开水。成人体液总量占体重的60-65%,其中细胞外液约占体重的20%。一个60公斤体重的人其体液总量约为36升,其中组织间液约9升,血浆约3升,细胞内液约20升。血浆与组织液比量不大,但流速很快,是体内物质交换的主要媒介。组织间液存
Water is an indispensable main component of the human body and is also a good medicine for health care, disease prevention and treatment. For example, because of illness 1 week does not enter food, but as long as the drinking water can sustain its life, if not drinking water, even a week is difficult to survive.

A body weight of 60 kg body weight of its total body volume of about 36 liters, of which interstitial fluid about 9 liters, about 3 liters plasma, about 20 liters of intracellular fluid. Plasma and tissue fluid ratio is not large, but the flow rate is fast, is the main medium for the exchange of matter. Inter-organizational liquid storage
