  1. What are the common diseases associated with the hepatobiliary system?
    • cirrhosis- esophageal varices
    • ascites
    • hepatitis
    • cholelithiasis
    • medical/surgical jaundice
    • hemangioma
    • hepatoma- hepatoblastoma- #1 pediatric tumor
    • pancreatitis
  2. Which disease of the hepatobiliary system is the #1 pediatric tumor?
  3. What are the functions of the liver?
    • metabolism
    • synthesis
    • detoxification
    • excretion
  4. What does the two blood supply of the liver do?

    • causes impaired liver function
    • portal hypertension= PHTN
    • development of:
    • collateral venous connections to vena cava
    • such connections involve the esophageal veins, which dilate to become esophageal varices
    • High risk of hemmorhage due to the inability for liver to make clotting factors or esophageal variceal rupture
