Liver sinusoids are different from the rest of the body’s sinusoids since they have macrophage cells intercalated in between their endothelial cells. Kupffer cells have a different embryological origin, coming from the myeloid line in the reticuloendohelial system (also called mononuclear phagocyte system) and are related to the immune system.
A hepatocyte is a cell of the main parenchymal tissue of the liver. Hepatocytes make up 80% of the liver's mass. These cells are involved in: Protein synthesis;
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 portal triads, hepatocytes arranged in linear cords between a capillary network, and a central vein.
The degree of rise in conjugated bilirubin is directly proportional to the degree of hepatocyte injury. Viral hepatitis can also cause the rise in conjugated bilirubin. In parenchymal liver disease and incomplete extrahepatic obstruction, the rise in conjugated bilirubin is less than the complete common bile duct obstruction due to malignant ...
A liver sinusoid is a type of capillary known as a sinusoidal capillary, discontinuous capillary or sinusoid, that is similar to a fenestrated capillary, having discontinuous endothelium that serves as a location for mixing of the oxygen-rich blood from the hepatic artery and the nutrient-rich blood from the portal vein.
The LSECs contain 45% and 17% of the liver's total mass of pinocytic vesicles and lysosomes, and contain twice as many clathrin-coated pits per membrane unit, compared with two other major liver cells, Kupffer cells and hepatocytes, [5] reflecting the high capacity clathrin-mediated endocytic activity of LSECs.
The blood count typically shows decreased numbers of blood cells—including a decreased number of circulating red blood cells, white blood cells, and platelets. The bone marrow may show hemophagocytosis. The liver function tests are usually elevated. A low level of the protein albumin in the blood is common. [citation needed]
Enterohepatic circulation of drugs. Enterohepatic circulation is the circulation of biliary acids, bilirubin, drugs or other substances from the liver to the bile, followed by entry into the small intestine, absorption by the enterocyte and transport back to the liver.
