【病理组织切片】肝组织病理切片中的三带是什么意思?

【答案】 很多次辛苦的专业回答非常正确和辛苦却不能得分,很是失望,这次本不想回答,但看到你也是个热心人我就辛苦下算啦.
　　肝组织学上划分成小叶.小叶中心是中央静脉.在小叶周边是汇管区.在功能上,基于供氧肝可分为三带. 一带围绕汇管区,在哪里从肝动脉来的血液富含氧气.三带局限在中央静脉周,那里的氧供最差.二带处于二者之间.英文书上原文如下,国内教科书似乎很少这么讲.
　　Liver is divided histologically into lobules. The center of the lobule is the central vein. At the periphery of the lobule are portal triads. Functionally, the liver can be divided into three zones, based upon oxygen supply. Zone 1 encircles the portal tracts where the oxygenated blood from hepatic arteries enters. Zone 3 is located around central veins, where oxygenation is poor. Zone 2 is located in between.
