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]
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; Detoxification, modification, and excretion of exogenous and endogenous substances
The Liver Injury Scale classification (2018 revision) [1] [2] [10] Grade Subcapsular hematoma Laceration Vascular injury I <10% surface area <1 cm in depth - II: 10–50% surface area: 1–3 cm - III >50% or >10 cm >3 cm Any injury in the presence of a liver vascular injury or active bleeding contained within liver parenchyma IV: 25–75% of a ...
Cirrhosis, also known as liver cirrhosis or hepatic cirrhosis, chronic liver failure or chronic hepatic failure and end-stage liver disease, is an acute condition of the liver in which the normal functioning tissue, or parenchyma, is replaced with scar tissue and regenerative nodules as a result of chronic liver disease.
Chronic liver disease in the clinical context is a disease process of the liver that involves a process of progressive destruction and regeneration of the liver parenchyma leading to fibrosis and cirrhosis. [1] "Chronic liver disease" refers to disease of the liver which lasts over a period of six months.
Liver showing chronic passive congestion associated with tricuspid valve incompetence. So called 'nutmeg liver', Split nutmeg, for those who have never seen this appearance. Close up of congested liver showing the 'nutmeg' appearance. Congestive hepatopathy, is liver dysfunction due to venous congestion, usually due to congestive heart failure.
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 histo pathology, ballooning degeneration, formally ballooning degeneration of hepatocytes, is a form of liver parenchymal cell (i.e. hepatocyte) death. The name is derived from the fact that the cells undergoing this form of cell death increase in size ( balloon ).
