胆道是输送胆汁的管道,胆道的结构好似许多小溪汇集成大河。在肝脏里有很多细小的“胆小管”。它们逐级汇成直径更宽的左、右肝管,这两根管道合并后形成“胆总管”继续下行与十二指肠相通,这就是胆汁自肝内流向小肠的重要交通网络。 胆囊是胆道系统中的另一成员。它的外形近似梨状。胆囊分为胆囊底、体、颈三部分。胆囊颈部比较细。通过胆囊管与胆总管相接。胆囊壁并不很厚,分为三层,最里边的为粘膜层。胆囊长约为7—10厘米,宽为3—5厘米,胆囊大小存在个体差异。胆囊好
The biliary tract is the conduit for the delivery of bile. The structure of the biliary duct resembles many streams that converge into large rivers. There are many small “bile ducts” in the liver. They gradually merged into a wider diameter of the left and right hepatic duct, the two merged to form a “common bile duct” and continue to communicate with the duodenum, which is the flow of bile from the liver to the small intestine of the important transport network. The gallbladder is another member of the biliary system. Its shape is similar to pear shape. Gallbladder into the bottom of the gallbladder, body, neck three parts. Gallbladder neck is relatively small. Through the cystic duct and common bile duct phase. Gallbladder wall is not very thick, divided into three layers, the innermost layer of mucous membrane. Gallbladder is about 7-10 cm long, 3-5 cm wide, there are individual differences in gallbladder size. Good gallbladder
