1

What is jaundice?

Yellowing of the skin and sclera (white of eyes) by increased levels of Bilirubin

2

Bilirubin is the normal byproduct in the breakdown of _ _ _ which mainly occurs in the _

Red blood cells, Spleen

3

Bilirubin is used to form _ in the _

Bile, Liver

4

"Biliary tree"- A set of tubes connecting the _ to the 2nd part of the _

Liver, Duodenum

5

The Gall bladder is important for _ and _ of Bile.

Storage, Concentration

6

Bile is important for absorption of _ from the small intestine

Fats

7

The pancreas excretes _ enzymes into the 2nd part of the duodenum

Digestion

8

The _ is the largest organ in the body

Liver

9

What are the three functions of the liver?

1. Bile secretion
2. Glycogen storage
3. Other metabolic functions

10

With regards to quadrants of the abdomen and Rib level, where is the Liver found?

1. RUQ
2. Ribs 7-11

11

What anatomical structures are found inferior to the liver?

1. Gall bladder- also posterior
2. Hepatic flexure
3. Stomach

Right Hemi diaphragm is Superior to the liver

12

Which structures are directly posterior to the liver?(4)

Spleen, Right kidney, Right adrenal gland, IVC, Abdominal aorta

13

What are the anatomical divisions of the liver? (4)

1. Right Lobe
2. Left "
3. Caudal "
4. Quadrate "

14

What is the site of entrance of the portal triad structures called?

Porta hepatis

15

How many functional segments does the liver have? What surgical procedure is it relevant to

8
Segmentectomy's

16

What vascular supplies are found in each liver segment?

1. Branch of hepatic portal vein
2. Branch of hepatic artery
3. Bile drainage (bile duct)
4. Venous drainage (IVC)

17

Why is an increase in Central Venous Pressure directed to the liver?

IVC and hepatic veins lack valves so blood backflow occurs

18

The hepatic veins directing _ blood from the liver come together as _ (number) veins before joining the _

1. Deoxygenated
2. 3
3. IVC

19

The portal triad runs within the _ ligament

Hepatoduodenal

20

The hepatoduodenal ligament and the _ ligament form the _ Omentum

Hepatogastric, Lesser

21

What are the 3 main contents of the portal triad?

1. Hepatic portal vein
2. Hepatic artery proper
3. Bile duct

22

What is the first midline branch of the aorta?

Coeliac trunk

23

The coeliac trunk is _peritoneal and leaves the aorta at _ vertebral level

Retro, T12

24

Coeliac trunk supplies organs of the _gut

Fore

25

What are the 3 branches of the coeliac trunk?

1. Splenic Artery
2. Left gastric artery
3. Common hepatic artery

26

The spleen is an _peritoneal organ within the left _

Intra, hypochondrium

27

The spleen is protected by ribs _ - _

9-11

28

The spleen is posteriorly related to the _, anteriorly related to the _, inferiorly related to the _ and medially related to the _

Diaphragm, stomach, splenic flexure, left kidney

29

Main function of spleen?

Breakdown spleen to form bilirubin

30

What are the two major types of arteries supplying blood the stomach (R&L one)

1. R&L gastric arteries
2. R&L Gastro-omental arteries

Minor supplies
-Posterior gastric arteries
- short gastric arteries

31

The R&L gastric arteries run along the curvature of the _ omentum

Lesser

32

The R&L gastro-omental arteries run along the curvature of the _ omentum

34

The R&L hepatic arteries are branches of which artery?

Hepatic Artery Proper

35

Which blood vessels supply the majority of the livers blood?

Hepatic portal vein

36

The histological cells of the liver are called _ , the centre of which is a _ vein

Lobules, central

37

What are the two peritoneal pouches formed around the liver?

1. Hepatorenal recess (Morissons pouch)
2. Sub-phrenic recess

Both are found in the greater sac of the peritoneal cavity

38

Why are these pouches relevant in peritonitis?

Peritonitis can occur as a result of pus collection and access formation in the pouches
