Packet 13 - Hepatobiliary System

Question 1

Functional Unit of the Liver - the Hepatic Lobule

Capillaries that surround hepatocytes. Receive blood from vessels branching off the hepatic artery and portal vein, carry it through lobule to central vein. Central vein then empties into hepatc vein.

a. ) Hepatocytes
b. ) Sinusoids
c. ) Kupffer cells
d. ) Bile canaliculi

Answer 1

Sinusoids

Capillaries that surround hepatocytes.

Receive blood from vessels branching off the hepatic artery and portal vein, carry it through lobule to central vein.

Central vein then empties into hepatc vein.

Question 2

Functional Unit of the Liver - the Hepatic Lobule

Ducts found between rows of hepatocytes. Receive the bile from hepatocytes as it is made, eventually empty into hepatic duct.

a. ) Hepatocytes
b. ) Sinusoids
c. ) Kupffer cells
d. ) Bile canaliculi

Answer 2

Bile Canaliculi

Ducts found between rows of hepatocytes.

Receive the bile from hepatocytes as it is made, eventually empty into hepatic duct.

Question 3

Functional Unit of the Liver - the Hepatic Lobule

The functional cells of the liver. Arranged in double rows that radiate out from a central vein.

a. ) Hepatocytes
b. ) Sinusoids
c. ) Kupffer cells
d. ) Bile canaliculi

Answer 3

Hepatocytes

The functional cells of the liver.

Arranged in double rows that radiate out from a central vein.

Question 4

Functional Unit of the Liver - the Hepatic Lobule

Phagocytes that line the sinusoids. Filter out bacteria and foreign substances from portal circulation.

a. ) Hepatocytes
b. ) Sinusoids
c. ) Kupffer cells
d. ) Bile canaliculi

Answer 4

Kupffer Cells

Phagocytes that line the sinusoids.

Filter out bacteria and foreign substances from portal circulation.

Question 5

Common Liver Function Tests

Which 3 test results indicate liver inflammation/injury?

1. ) increased ALT 2.) increased bilirubin levels
2. ) prolonged prothrombin time 4.) increased AST
3. ) increased LD/LDH 6.) increased ALP
4. ) decreased serum protein/albumin levels
5. ) increased alkaline phosphate (ALP)

Answer 5

Question 6

Common Liver Function Tests

Which 2 tests indicate decreased ability of the liver to synthesize proteins?

1. ) increased ALT 2.) increased bilirubin levels
2. ) prolonged prothrombin time 4.) increased AST
3. ) increased LD/LDH 6.) increased ALP
4. ) decreased serum protein/albumin levels
5. ) increased alkaline phosphate (ALP)

Answer 6

Question 7

Common Liver Function Tests

Which two tests indicate decreased excretory function?

1. ) increased ALT 2.) increased bilirubin levels
2. ) prolonged prothrombin time 4.) increased AST
3. ) increased LD/LDH 6.) increased ALP
4. ) decreased serum protein/albumin levels
5. ) increased alkaline phosphate (ALP)

Answer 7
