Gallstones are associated with:
Risk of biliary cancer
Elevated blood phosphorus levels
Concretions in the gall bladder comprised of cholesterol and risk of biliary cancer
Concretions in the gall bladder comprised of cholesterol
Dull, constant pain

The composition of bile includes:
Surfactants
Trypsin
Ghrelin
Lipase
Bicarbonate
Surfactants
A portal triad consists of branches of:
portal vein, bile duct, hepatic artery
liver lobules
inferior vena cava, portal vein, bile canaliculi
hepatic artery with a linear arrangement of hepatocytes
hepatic artery, common bile duct and hepatic duct
portal vein, bile duct, hepatic artery
Drug molecules that undergo Phase II type metabolism which are secreted into the bile are subsequently:
Excreted in the feces
Eliminated by the kidney
Always subject to enterohepatic recirculation
Further oxidized by Phase I metabolism
Processed by the first pass effect
Excreted in the feces
The portal vein:
Is located centrally in each liver lobule
Brings bile from the liver to the systemic circulation
Drains directly into the superior vena cava
Supplies oxygenated blood to the liver
Transports blood from the mesenteric veins to the liver
Transports blood from the mesenteric veins to the liver
Prehepatic jaundice is typically due to:
Advanced age
Biliary obstruction
Drug-induced liver injury
Gastrointestinal malabsorption syndrome
Red blood cell disorders
Red blood cell disorders
Which of the following is highly contagious and may cause fatal encephalitis in very young infants?
Salmonella
Candida albicans
H .pylori
Herpes simplex
None of the choices are correct
Herpes simplex
Hemochromatosis is:
iron accumulation exclusively in the liver due to production of ferritin in the liver
Iron stored in Ito cells of the liver, leading to their transformation into myofibroblasts
wear and tear pigment accumulating in liver cells
accumulation of iron that can lead to liver failure
major cause of NALFD
accumulation of iron that can lead to liver failure
The physiological function of bile is:
to deliver digestive enzymes to the duodenum
emulsification of dietary fats
to raise the pH of the stomach contents
metabolism of drugs
precipitation of cholesterol from the diet
emulsification of dietary fats
Which of the following IS NOT a normal function of the liver?
