Gall-stones and diseases of the bile-ducts . e hepatic cells : although thematter has not been precisely determined, it is quitecertain that they arise in the most intimate associationwith the hepatic cells, and become obvious to themicroscope as minute intercellular passages (bilecanaliculi), which communicate with the bile-ductsramifying in the interlobular connective bile-ducts around the lobules possess connective-tissue walls and are lined with short columnarepithelium, but in the portal canals the ducts arelarger and the coats contain areolar tissue and plainmuscle-fibres; the epithelium is columnar (Fig. 1). THE BILE-DUCTS 3 The bile-ducts converge to the portal fissure, and,enlarging as they become confluent, issue as theright and the left hepatic duct respectively : theseconjoin to form the hepatic duct which issues fromthe transverse fissure of the liver and receives thecystic duct descending from the gall-bladder ; to-gether they form the common bile-duct which opens Vein Lymphatic Bile-ductLymphatic Artery. Fig. 1.—Transverse section of a portal canal. (After Schafer.) into the second part of the duodenum. The largeducts and the gall-bladder constitute the excretoryapparatus of the liver and are of such importancethat each will require detailed description. The excretory apparatus of the liver.—This consistsof the hepatic duct, the cystic duct, the gall-bladder,and the common bile-duct (Fig. 2). The hepatic duct, formed by the union of the 4 DISEASES OF THE BILE-DUCTS right and left hepatic duct, has an average diameterof 4 mm., and in length varies from 3 to 5 cm. It
