Cirrhosis of the liver is a disease due to progressive scarring of the liver caused by various liver diseases and other conditions such as chronic hepatitis, biliary disease, cystic fibrosis and alcohol abuse. The scarring from these diseases diminishes blood flow in the liver and reduces the liver’s capacity to produce essential proteins, nutrients and hormones and process toxins. Cirrhosis causes changes with obstruction to the blood flow to the liver, called portal hypertension, which can result in an enlarged spleen , ascites and varices and can cause gastrointestinal (GI) bleeding. Damage done to the liver by cirrhosis is irreversible, and advanced stages can be fatal.
The liver also makes bile. This is a greenish-yellow fluid that contains bile acids, bile pigments and waste products such as bilirubin. Liver cells pass bile into bile ducts inside the liver. The bile flows down these ducts into larger and larger ducts, eventually leading to the common bile duct. The gallbladder is like a 'cul-de-sac' reservoir of bile which comes off the common bile duct. After you eat, the gallbladder squeezes bile back into the common bile duct and down into the the first part of the gut, known as the duodenum. Bile in the gut helps to digest fats.
In the Eighth Season of the show, Randy leaves for Costa Rica (along with Lauren, who stayed in a nearby town), reappearing in only one episode when he came back for Christmas. On that occasion, Randy felt that so much had changed in his absence that he no longer fit in with the family, although confiding in Wilson aided his feelings. Unlike Tim and Brad, Randy is not good with his hands and does not enjoy working on crafts or the Hot Rod. Randy often relates more with his mother, with whom he shares his intelligence and enjoyment of acting (although Tim embarrassed Randy during one acting scene thanks to a malfunctioning stage prop). In another episode Randy's party with friends was ruined due to Tim putting on too many coats of floorwax-which resulted in his girlfriend getting a sprained ankle.
