The celiac trunk.

It runs posterior to the stomach, and superior to the pancreas.

19

The right gastro-omental on the greater curvature of the stomach.

20

What are the contents of the hepatoduodenal ligament?

Hepatic artery

Portal vein

Bile duct

21

What is the function of the portal vein?

It brings deoxygenated, nutrient rich blood from the GI tract to the liver.

22

What is the function of the hepatic artery?

It supplies oxygenated blood.

It further divides into the left and right hepatic arteries.

23

What do the right and left hepatic veins drain into?

The right and left sides of the inferior vena cava.

24

Do the hepatic veins follow the branching patterns of portal veins, hepatic ducts and the hepatic artery?

No

25

Where does the gall bladder and biliary tract lie?

In the hepatic fossa

26

Where does the fundus contact the anterior abdominal wall of the midclavicular line?

At the 9th or 10th costal cartilage

27

Where does the superior mesenteric artery arise from?

The aorta posterior to the neck of the pancreas.

28

What does the pancreas receive branches from?

The celiac and superior mesenteric arteries.

29

What is the first branch of the superior mesenteric artery?

An inferior pancreaticoduodenal.

30

Where do branches from the superior mesenteric artery meet branches from the gastroduodenal?

The anterior and posterior surfaces of the head of the pancreas.

31

Where does the superior mesenteric artery branch?

To the small intestine.

It containst he inferior pancreaticoduodenal artery, jejunal arteries and ileal arteries

34

What does the inferior mesenteric artery supply?

Derivativees of the hindgut.

It branches into the left colic artery and sigmoid arteries.

35

Where does the hepatic portal system begin?

As capillaries in the digestive system. It ends as capillaries in the liver.

It is oxygen poor, and nutrient rich.

It also dains blood from the esophagus to the upper anal canal.

36

What does the hepatic portal system end as?

Capillaries in the liver.

37

For about two inches of the protal vein, there are no valves.

Where does the hepatic portal system form?

Posterior to the neck of the pancreas.

It ends as the right and left branches in the liver.

40

Where does the hepatic portal system run?

Through the hepatoduodenal ligament to enter the liver at the porta hepatis.
