  有關(guān)肝的知識閱讀中英對照:

  一、Anatomy of the Liver

  he anterior surface of the liver is triangular in shape, made of two lobes. The right lobe is the larger of the two, measuring 6 to 7 inches in length. The left lobe is 3 inches in length.

  Ligaments connect the upper surface of the liver to the diaphragm and the abdominal wall and the under surface to the stomach and duodenum. The gall bladder is located on the under surface of the right lobe of the liver. Neighboring organs include the colon, the intestines, and the right kidney.

  肝臟解剖學(xué)

  肝的前面是三角形,由兩個(gè)葉組成。右葉較大,長6-7英寸。左葉長3英寸。

  肝的上面由韌帶連接著膈肌和腹壁,下面連接著胃和十二指腸。膽囊位于肝右葉的下方。它的鄰近器官是結(jié)腸、小腸和右腎。

  二、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.

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

  A central vein runs through the middle of the lobe 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.

  肝的微細(xì)結(jié)構(gòu)

  在顯微鏡下,肝臟是由肝小葉為單位的網(wǎng)狀結(jié)構(gòu)。肝小葉非常小,是六棱柱體。

  小葉的周圍是結(jié)締組織,邊緣圍繞著5-7串脈管,有門靜脈、肝動(dòng)脈和膽小管。

  小葉的中央由中央靜脈穿過,周圍被向四周呈放射狀排列的肝細(xì)胞索包圍。在索之間是擴(kuò)大了的毛細(xì)血管叫血竇。所有的血液都流入肝靜脈參與體循環(huán)。
