    Notes: Summary The three-dimensional structure of the bile ducts and their relationship to the blood vessels were studied in the larval lamprey by scanning electron microscopy of the intact tissue and of biliary and vascular casts. The intrahepatic gall bladder is situated in the cephalic portion of the liver and a cystic duct is connected to a straight intrahepatic common bile duct, which extends to the extrahepatic bile duct at the caudal end of the liver. Several smaller intrahepatic common bile ducts are connected directly to the intrahepatic common bile duct, are convoluted or serpiginous and are surrounded intimately by sinusoids. This arrangement enables the bile ducts to have increased surface area exposed to blood vessels. The functional significance of this arrangement is discussed with respect to the modification of bile through the transport of solutes and the similarity of this bilio-vascular relationship to the peribiliary vascular plexus of the mammalian liver.

    Three-dimensional observation of the intrahepatic lymphatics by scanning electron microscopy of corrosion casts (1986)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: The three-dimensional arrangement of intrahepatic lymphatics was demonstrated in the rabbit liver by scanning electron microscopy of corrosion casts. These casts were prepared by injecting resin into the common bile duct at a pressure that caused resin to leak from the bile ducts in the small portal tracts and drain into the lymphatics. The lymphatic channels were composed of straight vessels and anastomosing short side branches. The anastomoses were especially rich at the bifurcation of the portal tracts and formed a network. The terminal branches were blind-ended. Constrictions suggesting valves were occasionally observed.
