Intracellular Accumulation Build-up of substances like fat or copper in the liver Wilson disease a congenital disorder that causes a person to retain excess copper Apoptosis Programmed cell death in liver cells. Regeneration Liver cell replacement after injury or resection. Inflammation Hepatocyte injury with inflammatory cell influx. Fibrosis Scar tissue formation in response to inflammation or direct toxic result Progressive fibrosis with nodular liver regeneration Caused by Alcohol, chronic hepatitis, biliary disease, iron overload. Hallmarks: • Bridging fibrous septa • Parenchymal nodules • Disrupted liver architecture Ductular Reaction Biliary ductule proliferation with fibrosis and inflammation. Acute Liver Failure Type of liver failure w/Massive necrosis, often from drugs or viruses. Chronic Liver Disease Type of liver failure w/Long-term liver damage leading to cirrhosis. Hepatic Dysfunction Type of liver failure with viable hepatocytes unable to function normally. Not overtly necrotic Jaundice Yellowing of skin due to bile retention. Unconjugated hyperbilirubinemia Excess bilirubin production, hepatic uptake defects, impaired conjugation. Conjugated hyperbilirubinemia Decreased hepatocellular excretion, impaired bile flow. Bile function Eliminates bilirubin, cholesterol, xenobiotics, and emulsifies dietary fat. Cholestasis Bile retention due to liver dysfunction or blockage Symptoms: Skin xanthomas (cholesterol deposits), elevated alkaline phosphatase Hepatic Encephalopathy Complication of acute & chronic liver failure with brain dysfunction. Symptoms range from behavioral changes to coma & death. Asterixix may be present Asterixis "Flapping tremor" (nonrhythmic extension-flexion movements). Acute hepatic encephalopathy
