Concept ·1、人体体液的组成: The total body water is comprised of several different compartments. Water in the body is divided into two main compartments separated by the cell membrane Intracellular fluid(CF), consisting ofallfluid with in the cell membrane of the body, is the largestfluid compartment It accounts for about 30 to 40 percent ofbody weight. --Extracellular fluid(ECF), consisting of the water outside the cells. ECFincludes interstitialfluid and plasma 2、电解质: 体液中有无机物和有机物,无机物与部分以离子形式 存在的有机物统称为电解质。Na+是细胞外主要的阳 离子,K+是细胞内主要的阳离子;细胞内主要的阴 离子是蛋白质与磷酸根,而细胞外则是C与HCO: 葡萄糖、尿素等不能解离的有机物称为非电解质,尿素 与肌酐浓度是衡量肾功能状态的指标。一、 Concept • 1、人体体液的组成：The total body water is comprised of several different compartments.Water in the body is divided into two main compartmentsseparated by the cell membrane. --Intracellular fluid(ICF),consisting of all fluid with in the cell membrane of the body,is the largest fluid compartment.It accounts for about 30 to 40 percent of body weight. .--Extracellular fluid(ECF),consisting of the water outside the cells.ECF includes interstitial fluid and plasma. 2、电解质： 体液中有无机物和有机物，无机物与部分以离子形式 存在的有机物统称为电解质。Na＋是细胞外主要的阳 离子，K＋是细胞内主要的阳离子；细胞内主要的阴 离子是蛋白质与磷酸根，而细胞外则是Cl-与HCO3 - . 葡萄糖、尿素等不能解离的有机物称为非电解质,尿素 与肌酐浓度是衡量肾功能状态的指标
