1

Radiographic examination of the biliary system involves studying the

manufacture, transport, and storage of bile.

2

Liver:

Large wedge-shaped organ
Located inferior to the diaphragm.
Largest solid organ
3-4 lbs
Occupies most of RUQ and extends to LUQ
Well protected by rib cage.

3

Describe the upper border of the liver:

Widest part 8 to 9”
Convex to conform to diaphragm

4

Describe the right border of the liver:

Largest vertical dimension 6-7”
10th rib to just above R. Kidney

5

Distal end of gall bladder extends:

below anterior, inferior margin of liver

6

Remainder of GB (when discussing the distal end) lies

inferior and posterior surface of liver

7

The right lobe and left lobe of the liver are divided by:

the falciform ligament.

8

The quadrate lobe and caudate lobe are located:

on medial aspect of R. Lobe of the liver.

9

The quadrate lobe is located:

Between GB and falciform ligament

10

The caudate lobe is located:

Posterior to quadrate lobe

11

Hilum of liver (porta hepatitis) is located:

between the 2 minor lobes

12

The function of the liver that is most applicable to radiographic study is:

the production of bile

13

The liver secretes _________of bile per day

800 to 1000 ml (≈ 1 quart)

14

The major function of bile is:

to aid in the digestion of fats by emulsifying fat globules and the absorption of fat following its digestion.

15

Bile is a liquid substance composed mainly of

bile salts, bile pigments, cholesterol and water.

16

Bile pigments are responsible for

the yellow color of bile.

17

Bile salts facilitate

the absorption of fats.

18

If bile contains either insufficient bile salts or excessive cholesterol,

the cholesterol may crystallize to form gallstones.

19

As gallstones grow in size and number, may cause

minimal, intermittent, or complete obstruction of the flow of bile from the gallbladder into the duodenum.

20

Bile formed in liver and travels to

R&L hepatic ducts

21

Hepatic ducts join to form

common hepatic duct

22

Bile is carried to gallbladder by _____ for temporary storage in gallbladder or may be secreted directly into duodenum by way of ______ which is joined by _________.

cystic duct, common bile duct, pancreatic duct

23

How big is the gall bladder and how much does it hold?

7 to 10 cm (3-4”) long
Holds about 30 to 40 mL bile

24

What are the three parts of the gall bladder?

Fundus:
Broad distal end
Body:
Main section
Neck:
Narrow proximal end
Continues as cystic duct

25

How long is the cystic duct?

3 to 4 cm long

26

What is the function of the spiral valve?

to prevent distention or collapse of cystic duct.

27

What and where is the spiral valve?

The spiral valve is folds within the cystic duct.

28

The three primary functions of the gallbladder are

(1)store and (2)concentrate bile, and to (3)contract when stimulated.

29

If bile is not needed for digestive purposes, it is:

stored for future use in the gallbladder.

30

Bile is concentrated within the gallbladder as a result of a process called

hydrolysis (removal of water).
