WebNov 28, 2024 · The two main surfaces of the liver are the diaphragmatic surface and the visceral surface. The latter is covered by visceral peritoneum except at the porta hepatis and the bed of the gallbladder. This surface is directly related to several anatomical structures which include the: duodenum gallbladder hepatic flexure of colon transverse colon WebThe hepatic duct joins the cystic duct from the gallbladder to form the common bile duct. However what produces this bile is the hepatocytes themselves. The bile is secreted into …

The limiting plate is a layer of hepatocytes surrounding the portal tact. In chronic hepatitis, this pattern of injury is an indicator of activity and is usually followed by fibrosis (Fig. 4).

Terminal branches of the hepatic veins are in the center of hepatic lobules. WebHuman hepatic portal structures are supported by a greater amount of collagen, as well as thin reticular fibers (consisting of type III collagen), that form a loose network supporting the sinusoids. Due to their size and associated connective tissue, portal regions in the human liver are readily apparent even at low magnification.
