b. eliminate waste products
c. both
d. neither

A

C

30
Q

The mixture of primary and secondary bile salts and bile acids is primarily absorbed in _______

A

terminal ileum

31
Q

conjugation reactions- glucoronate, acetate, glutathione, glycine, sulfate and methyl group additions – Smooth ER

a. PHASE I
b. PHASE II

35
Q

Impaired bile flow from liver to duodenum either intra or extrahepatic etiology

a. cholecystitis
b. cholangitis
c. cholelithiasis
d. cholestasis

A

D

36
Q

Extrahepatic

a. indirect bilirubin elevation
b. direct bilirubin elevation

37
Q

found in liver, bile duct epithelium and bones

38
Q

hepatocytes and biliary epithelium, sensitive to biliary disease if Alk Phos is elevated

A

GGT

39
Q

Bilirubin levels when jaundice becomes apparent

A

2.5-3 mg/dL

40
Q

A mild liver disorder in which the liver does not properly process bilirubin. This disease is due to a mutation in the UGT1A1 gene which results in decreased activity of the bilirubin uridine diphosphate glucuronosyltransferase enzyme.

A

Gilbert’s Syndrome

41
Q

This is a rare inherited disorder affecting the metabolism of bilirubin, a chemical formed from the breakdown of the heme in red blood cells. The disorder results in a form of nonhemolytic jaundice, which results in high levels of unconjugated bilirubin and often leads to brain damage in infants.

A

Crigler-Najar Syndrome

42
Q

defect in transport protein of bilirubin, no pigmentation of liver

a. Gilbert’s syndrome
b. Crigler-Najar Syndrome
