17
Q

How do you find the inferior mesenteric artery on a prosection?

A

Short gastric arteries
Left gastroepiploic artery
Right gastroepiploic artery

23
Q

What are the branches of the splenic artery?

A

Left gastroepiploic artery

24
Q

Right gastric artery

25
Q

A

Superior pancreticoduodenal artery
Right gastroepiploic artery

26
Q

What is the blood supply to the gall bladder?

A

Cystic artery
Branches off the right hepatic artery

27
Q

What drains the midgut?

A

Superior mesenteric vein

28
Q

What drains the foregut?

A

Splenic vein

29
Q

What drains the hindgut?

A

Superior rectal vein > inferior mesenteric vein

30
Q

Why is the superior mesenteric vein so large?

A

The majority of reabsorption occurs in the small intestine (midgut) so large volume of blood needs to be filtered by the liver

31
Q

What drains into the hepatic portal vein?

A

Superior mesenteric vein
Splenic vein
(Inferior mesenteric vein)

32
Q

State the veins from the rectum to the liver

A

Superior rectal vein
Inferior mesenteric vein
Splenic vein
Hepatic portal vein

33
Q

Where does the cystic artery branch off?

A

Right hepatic artery

34
Q

Where does the right gastroepiploic artery branch from?

A

Gastroduodenal artery

35
Q

Where do the superior and inferior pancreaticoduodenal arteries arise from?

A

Superior - gastroduodenal artery
Inferior - SMA
