Blood supply to the gut

Question 1

Which artery supplies the foregut

Answer 1

the celiac trunk

Question 2

the celiac trunk can be divided into 3 main branches

Answer 2

• common hepatic (to the right)
• splenic artery (to the left)
• Left gastric (superiot left)

Question 3

the common hepatic artery route

Answer 3

It passes anterior to the pancreas, and then inferiorly to the right in the lesser sac towards the first part of duodenum. It gives off the right gastric artery, which runs superiorly along the right half of the lesser curvature of the stomach to anastomose with the left gastric artery. The common hepatic artery then passes slightly upwards where it runs anterior to the portal vein and medial to the common bile duct in the free edge of the lesser omentum. As it courses towards the porta hepatis it gives off the gastroduodenal artery inferiorly, after which it becomes the proper hepatic artery.

Answer 4

Question 5

branches of the superior mesenteric

Answer 5

• middle colic
• right colic

Question 6

middle colic supplies the

Answer 6

the transverse colon.

It arises just below the pancreas. It passes inferiorly and anteriorly between the layers of the transverse mesocolon, and divides into left and right branches.

Question 7

Answer 9

illeum and jejunum
