高二生物辅导（一） 必修三第一章 一、内环境 1. 内环境是指由细胞外液构成的液体环境，是机体内细胞生活的直接环境。 （1）血浆：血细胞直接生活的环境。 （2）组织液（又叫细胞间隙液）：体内绝大多数细胞直接生活的环境。 （3）淋巴液（也叫淋巴）：淋巴管内的吞噬细胞和淋巴细胞直接生活的环境。 2、各种细胞的内环境 ①血细胞直接生活的环境：血浆； ②毛细血管壁细胞直接生活的环境：血浆和组织液； ③毛细淋巴壁细胞直接生活的环境：淋巴和组织液； ④体内绝大多数组织细胞直接生活的环境：组织液 3、内环境的成分 （1）人的呼吸道、肺泡腔、消化道、泪腺等有孔道与外界相通的结构中的液体应视为外部环境。如尿液、泪液、消化液等不是细胞外液。营养废物和气体，激素抗体与递质，胞内物质都不是。血红蛋白(红细胞内)、载体蛋白和过氧化氢酶等各种胞内酶，它们属于细胞内液的成分。 ( 2 ) 属于内环境的成分 ①营养成分：氧气、水、无机盐、葡萄糖、甘油、脂肪酸等。 ②代谢产物：激素、维生素、抗体、组织胺、神经递质等。 ③代谢废物：二氧化碳、尿素等。 二、细胞外液的化学成分 1、血浆：90%以上是水,是蛋白质, 10%是糖类,无机盐类,代谢产物等 2、组织液、淋巴的成分和含量与血浆相近，但又不完全相同，“最主要”的差别是血浆中含有较多的蛋白质，而组织液和淋巴中的蛋白质含量很少。 三、细胞外液的理化特性 1、溶液的渗透压：是指溶液中溶质微粒对水的吸引力。溶液渗透压的大小取决于单位体积溶液中溶质的微粒的数目，溶质微粒越多，溶液浓度越高，对水的吸引力越大，溶液渗透压越高。由于血浆中含有无机盐和蛋白质，故血浆渗透压与其有关。
