Intrahepatic bile ducts compose the outflow system of exocrine bile product from the liver. They can be divided into: [2] Lobar ducts (right and left hepatic ducts) - stratified columnar epithelium. Interlobar ducts (between the main hepatic ducts and the interlobular ducts) - pseudostratified columnar epithelium.
The interlobular bile ducts (or interlobular ductules) carry bile in the liver between the Canals of Hering and the interlobar bile ducts. [1] They are part of the interlobular portal triad and can be easily localized by looking for the much larger portal vein .
The canals of Hering are destroyed early in primary biliary cholangitis and may be primary sites of scarring in methotrexate toxicity.Research has indicated the presence of intraorgan stem cells of the liver that can proliferate in disease states, so-called oval cells. [5]
The front border of the liver has been lifted up (brown arrow). [1] A bile duct is any of a number of long tube-like structures that carry bile, and is present in most vertebrates. The bile duct is separated into three main parts: the fundus (superior), the body (middle), and the neck (inferior).
An intralobular duct is the portion of an exocrine gland inside a lobule, leading directly from acinus to an interlobular duct (between lobules). It is composed of two subdivisions, the intercalated duct and the striated duct. In the human mammary gland, the intralobular duct is a part of the glandular system that resides within the lobules.
The function of the common bile duct is to allow bile to travel from the gallbladder to the small intestine, mixing with pancreatic digestive enzymes along the way. [4] One possible complication of choledocholithiasis is an infection of the bile ducts between the liver and the gallstone lodged in the common bile duct.
In histology (microscopic anatomy), the lobules of liver, or hepatic lobules, are small divisions of the liver defined at the microscopic scale. The hepatic lobule is a building block of the liver tissue , consisting of a portal triad, hepatocytes arranged in linear cords between a capillary network, and a central vein .
Cholangiocytes are the epithelial cells of the bile duct. [1] They are cuboidal epithelium in the small interlobular bile ducts, but become columnar and carbonate-secreting in larger bile ducts approaching the porta hepatis and the extrahepatic ducts. They contribute to hepatocyte survival by transporting bile acids.
