  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?
    Hepatic Artery- delivers oxygenated blood

    Portal Vein- returns venous blood from abdominal viscera-nutrient rich (formed by superior mesenteric and splenic veins)
  5. What is the function of the gallbladder?
    store and concentrate bile
  6. What is the function of the pancrease?
    • both exocrine and endocrine
    • Exocrine- trypsin (digestion of proteins), amylase (starch), lipase (lipids).
    • Via pancreatic duct to duodenum

    • Endocrine-
    • Insulin- hyperglycemic
    • Glucagon- hypoglycemic - liver break down glycogen
    • Via islets of Langerhans
  7. What is cirrhosis?
    • liver parenchyma/architecture destroyed
    • asymptomatic in early stages
    • end stage of chronic alcoholism
    • 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
  8. What is ascites?
    • fluid within peritoneal cavity
    • may result from hepatitis, renal failure, cancer and CHF
