The hepatocyte is a cell in the body that manufactures serum albumin, fibrinogen, and the prothrombin group of clotting factors (except for Factors 3 and 4). It is the main site for the synthesis of lipoproteins, ceruloplasmin, transferrin, complement, and glycoproteins. Hepatocytes manufacture their own structural proteins and intracellular ...
Lobules of liver. The structure of the liver’s functional units or lobules. Blood enters the lobules through branches of the portal vein and hepatic artery proper, then flows through sinusoids. In histology (microscopic anatomy), the lobules of liver, or hepatic lobules, are small divisions of the liver defined at the microscopic scale.
Definitions. Cytology is the name given to the branch of biology that deals with the formation, structure and functionality of the cells. [1] Liver cytology specializes in the study of liver cells. The main liver cells are called hepatocytes; however, there are other cells that can be observed in a liver sample such as Kupffer cells ...
Hepatic stellate cells (HSC), also known as perisinusoidal cells or Ito cells (earlier lipocytes or fat-storing cells), are pericytes found in the perisinusoidal space of the liver, also known as the space of Disse (a small area between the sinusoids and hepatocytes). The stellate cell is the major cell type involved in liver fibrosis, which is ...
Structure. The liver, viewed from above, showing the left and right lobes separated by the falciform ligament. The liver is a dark reddish brown, wedge-shaped organ with two lobes of unequal size and shape. A human liver normally weighs approximately 1.5 kilograms (3.3 pounds) [11] and has a width of about 15 centimetres (6 inches). [12]
Liver sinusoid. Sinusoid of a rat liver with fenestrated endothelial cells. Fenestrae are approx 100 nm diameter, and the sinusoidal width 5 µm. 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 ...
Anatomical terms of microanatomy. [edit on Wikidata] The perisinusoidal space (or space of Disse) is a space between a hepatocyte, and a sinusoid in the liver. It contains the blood plasma. Microvilli of hepatocytes extend into this space, allowing proteins and other plasma components from the sinusoids to be absorbed by the hepatocytes.
Anatomical terms of microanatomy. [edit on Wikidata] Kupffer cells, also known as stellate macrophages and Kupffer–Browicz cells, are specialized cells localized in the liver within the lumen of the liver sinusoids and are adhesive to their endothelial cells which make up the blood vessel walls. Kupffer cells comprise the largest population ...
