The Liver Up Close

  When viewed under a microscope, the liver is seen as large network of units called hepatic lobules. The hepatic lobule is very small and looks like a six-sided cylinder 1.

  The lobule itself is surrounded by connective tissue and has 5 to 7 clusters of vessels 2 around its edges. These vessels include a branch of the portal vein 3, a branch of the hepatic artery 4, and a bile duct.

  A central vein runs through the middle of the lobe 5 and is surrounded by cords of liver cells that radiate out in all directions. Between these cords are wide thinwalled blood vessels called sinusoids. All of the blood drains into a hepatic vein which then circulates throughout the body.

  肝的微细结构

  在显微镜下,肝脏是由肝小叶为单位的网状结构。肝小叶非常小,是六棱柱体。

  小叶的周围是结缔组织,边缘围绕着5-7串脉管,有门静脉、肝动脉和胆小管。

  小叶的中央由中央静脉穿过,周围被向四周呈放射状排列的肝细胞索包围。在索之间是扩大了的毛细血管叫血窦。所有的血液都流入肝静脉参与体循环。
