补充资料:肺泡
由单层上皮细胞构成的半球状囊泡。肺中的支气管经多次反复分枝成无数细支气管,它们的末端膨大成囊,囊的四周有很多突出的小囊泡,即为肺泡。肺泡的大小形状不一,平均直径0.2毫米。成人约有3~4亿个肺泡,总面积近100平方米。肺泡是肺部气体交换的主要部位,也是肺的功能单位。氧气从肺泡向血液弥散,要依次经过肺泡内表面的液膜、肺泡上皮细胞膜、肺泡上皮与肺毛细血管内皮之间的间质、毛细血管的内皮细胞膜等四层膜。这四层膜合称为呼吸膜。呼吸膜平均厚度不到1微米,有很高的通透性,故气体交换十分迅速。血液中的二氧化碳弥散出肺时,要通过与上述相反的途径。肺泡内的表面液膜含有表面活性物质,起着降低肺泡表面液体层表面张力的作用,使细胞不易萎缩,且吸气时又较易扩张。肺组织缺氧时,会使肺表面活性物质分泌减少,进入肺泡的水肿液或纤维蛋白原可降低其表面活性物质的活力,引起肺内广泛的肺泡不张,血液流经这些萎陷肺泡的毛细血管时就不能进行气体交换。临床上新生婴儿患肺不张症,就是因为缺乏肺表面活性物质所致。相邻两肺泡间的组织为肺泡隔,内有丰富的毛细血管及弹性纤维、网状纤维。弹性纤维包绕肺泡,使肺泡具良好弹性。患慢性支气管炎或支气管哮喘时,肺泡长期处于过度膨胀状态,会使肺泡的弹性纤维失去弹性并遭破坏,形成肺气肿,影响呼吸机能。
