List 5 known viruses that affect the liver?
1. Hepatitis A
2. Hep. C
3. Hep. D
4. Hep. E
5. Hep G

Hep A/E are both transmitted vis the fecal-oral route, while the rest are transmitted via blood to blood contact.
In acute viral hepatitis, the hepatocytes produce enzymes that are released during cell death. TRUE/FALSE
TRUE.
These are the liver function enzymes aspartate aminotransferase(ALT), gammaglutamyl transpeptidase(GGT), and alkaline phosphatase.(AP)
What is the enzyme differentiation regarding viral and gall stone hepatitis?
Viral hepatitis usually causes ALT and AST to elevate to very high levels, while GGT and AP and bilirubin are only mildly elevated.
A gall stone in the bile duct causes the opposite. Bilirubin, AP and GGT rise higher than ALT and AST.
The hepatitis produce AST and ALT. TRUE/FALSE
TRUE.
The cells that line the bilecanaliculi produce AP and GGT. The bile caniliculi carry bilirubin.
With viral hepatitis there is cell necrosis as the virus takes over the cell machinery. The hepatocytes rupture resulting in the release of AST and ALT. TRUE/FALSE
TRUE.
