1

What is the first branch of the abdominal aorta?

The coeliac trunk.

2

What level does the coeliac trunk leave the abdominal aorta?

T12.

3

What does the coeliac trunk supply?

The foregut organs.

4

What 3 arteries does the coeliac trunk trifurcate into?

Common hepatic artery
Left gastric artery
Splenic artery

5

What does the common hepatic artery divide into?

Gives off the gastroduodenal artery and becomes the hepatic artery proper.

6

What does the left gastric artery anastamose with and where?

The right gastric artery.
As it runs along the lesser curvature of the stomach.

7

What does the hepatic artery proper bifurcate into?

The right and left hepatic arteries.

8

What do the right and left hepatic arteries supply?

The right and left lobes of the liver.

9

Which artery gives the cystic artery?

The right hepatic artery.

10

What does the cystic artery supply?

The gallbladder.

11

Where does the right gastro-omental artery come from?

The gastroduodenal artery.

12

Where does the right and left gastro-omental arteries anastamose?

The greater curvature of the stomach.

13

What arteries comes off the splenic artery?

Left gastro-omental artery
Posterior gastric artery
Short gastric arteries.
Dorsal pancreatic arteries

14

Which arteries does the gastroduodenal artery give?

Right gastro-omental artery
Superior pancreaticoduodenal artery

15

What does the superior pancreaticoduodenal artery anastamose with and where?

Inferior pancreaticoduodenal artery (branch of the SMA)
Around the head of the pancreas.

16

Where does the SMA leave the aorta?

L1
Posterior to the neck of the pancreas

17

What group of organs does the SMA supply?

Midgut organs.

18

Which branch of the SMA supplies the jejunum and ileum?

Jejunal and ileal branches.

19

Which branch of the SMA supplies the appendix?

The appendicular branch.

20

Which branch of the SMA supplies the caecum?

Ileocolic branch

21

Which branch of the SMA supplies the ascending colon?

Right colic artery

22

Which branch of the SMA supplies the transverse colon?

Middle colic artery

23

Which arteries supply blood to both the pancreas and the duodenum?

The inferior pancreaticoduodenal artery anastomoses with the superior pancreaticoduodenal artery.

24

What level does the IMA leave the aorta?

L3
Slightly left of the midline.

25

What group of organs is supplied by the IMA?

Hindgut.

26

Which branch of the IMA supplies the descending colon?

Left colic artery

27

Which branch of the IMA supplies the sigmoid colon?

The sigmoid arteries

28

Which branch of the IMA supplies the rectum?

The superior rectal arteries

29

What does anastomosis between SMA and IMA allow for?

Collateral circulation
Called marginal artery of Drummond.

30

What level does the aorta bifurcate into the common iliacs?

L4

31

Where does the internal iliac arteries supply?

The GI tract after the pectinate line via the middle and inferior rectal arteries.

32

Where do the internal iliac veins drain to?

IVC

33

Where does the hepatic portal vein drain?

Blood from the foregut, midgut and hindgut organs to the liver (for first pass metabolism).

34

What 2 veins join to form the hepatic portal vein?

Splenic vein
Superior mesenteric vein.

35

Where does the inferior mesenteric vein drain from and to?

From the hindgut organs to the splenic vein.

36

Where does the IVC drain cleaned blood from the hepatic veins?

Into the right atrium.

37

What is the first branch of the ascending aorta?

The coronary arteries

38

Where is the left coronary artery found?

In the left atrioventricular groove.

39

What is the atrioventricular groove found between?

Between the pulmonary trunk and the left auricle.

40

Which arteries come off the left coronary artery?

Left anterior descending artery (LAD)
Left marginal artery
Circumflex artery

41

Which coronary artery anastamoses with the right coronary artery?

Circumflex artery

42

Where is the right coronary artery found?

Right atrioventricular/ coronary groove.

43

How do you visualise the right coronary artery?

Retract the right auricle.

44

Which arteries come off the right coronary artery?

Right marginal artery

45

What is the coronary sinus?

A short venous conduit, receives deoxygenated veins from most cardiac veins and drains into the right atrium.
