The liver parenchyma is the functional tissue of the organ made up of around 80% of the liver volume as hepatocytes. The other main type of liver cells are non-parenchymal. Non-parenchymal cells constitute 40% of the total number of liver cells but only 6.5% of its volume. [11]
Anatomical terms of microanatomy. [edit on Wikidata] 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. Protein storage. Transformation of carbohydrates. Synthesis of cholesterol, bile salts and phospholipids.
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]
Other causes include: infiltrative liver diseases, granulomatous liver disease, abscess, amyloidosis of the liver and peripheral arterial disease. Mild elevation of ALP can be seen in liver cirrhosis, hepatitis, and congestive cardiac failure. Transient hyperphosphataemia is a benign condition in infants, and can reach normal level in 4 months.
Cirrhosis, also known as liver cirrhosis or hepatic cirrhosis, and end-stage liver disease, is a condition of the liver in which the normal functioning tissue, or parenchyma, is replaced with scar tissue (fibrosis) and regenerative nodules as a result of chronic liver disease. [ 6 ][ 7 ][ 8 ] Damage to the liver leads to repair of liver tissue ...
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 .
In the adult liver, most of the cells are binucleated, and most of the hepatocytes are tetraploid, which means that they have four times the amount of normal DNA. Their average lifespan is from approximately five months, and hepatocytes have a significant regeneration capacity after parenchymal loss by toxic processes, diseases or surgeries.
In some cases this accumulation can mimic a liver tumor. Sometimes the opposite phenomenon can be seen, that is an "island" of normal parenchyma in a “shining” liver. In both cases ultrasound examination identifies a well defined, un-encapsulated area, with echostructure and vasculature similar to those of normal liver parenchyma.
