Flashcards in Functional Histology of the Liver Deck (22):
1

The surrounding capsule around the liver is called _______________.

Glisson's capsule

2

The hilum of the liver is called _____________.

the porta hepatis

3

The hepatic portal vein carries about _______ percent of the blood to the liver.

75%

4

The bile duct, as it enters the liver, is called the ___________.

hepatic duct

5

True or false: the hepatic artery follows the hepatic vein in the liver.

False. The hepatic artery follows the hepatic portal vein. The hepatic portal vein drains blood across the hepatocytes to the hepatic veins, which carries the filtered product into the inferior vena cava.

6

Which vessel in the liver has cuboidal lining?

The bile duct

7

The lymphatic travels with what vessels?

Hepatic artery
Portal vein
Bile duct

8

Plates of hepatocytes lead to the _____________.

central vein

9

In cases of poisoning, the ____________ die first. In cases of ischemia, however, the ____________ die first.

cells near the hepatic triads; cells near the central vein

10

Kupffer cells are _______________.

the macrophages of the liver

11

Fenestrated endothelial cells are connected to hepatocytes across the ________________ by reticular fibers. Plasma is able to cross this space through the fenestrated endothelium. (RBCs are too big.)

space of Disse

12

Ito cells, which lie between hepatocytes, store _______________.

lipid and vitamin A

13

The portal triads are arranged hexagonally around _____________.

central veins

14

Portal lobules are _________________.

triangular

15

The portal lobule outlines the _________________.

flow of bile into bile ducts (since portal lobules cover the area around a portal triad)

16

Toxic injury tends to affect the center of the ___________ lobule.

acinar (which outlines hepatic artery)

17

True or false: the hepatocytes near the central veins typically make coagulation factors while the hepatocytes near the hepatic arteries make albumin.

False. All hepatocytes make the full complement of protein.

18

The endothelial lining of the sinusoids is _____________ to allow plasma constituents to pass through.

fenestrated

19

The space between the endothelium and the hepatocytes is called _____________.

the space of Disse (with collagenous fibers crossing)

20

How much bile is produced daily?

500 mL

21

Chemically, what does the liver do to double bonds?

It catalyzes an epoxide reaction that produces a hydroxyl group, which then gets conjugated.

22

Ito cells lie between ________________ and contain ______________.

sinusoid hepatocytes; fat-soluble vitamins
