Vascular Supply of the Forgut Flashcards
All organs associated with the foregut receive their arterial supply from branches off the _____ ____.
Celiac trunk.
Is an unpaired artery arising from the anterior abdominal aorta immediately below the aortic hiatus of the diaphragm (T12).
Celiac trunk.
What are the 3 branches of the celiac trunk?
Left gastric artery, splenic artery, and the common hepatic artery.
Courses within the lesser omentum and supplies the lesser curvature of the stomach and inferior portion of the esophagus; from anastomosis with the right gastric artery.
Left gastric artery.
Follows a highly tortuous course along the superior border of the pancreas; terminates by passing between the layers of the splenorenal ligament and supplying the spleen.
Splenic artery.
What are the 4 branches of the splenic artery?
Left gastroomental (gastroepiploic) artery, short gastric artery, pancreatic arteries, and the posterior gastric artery.
Courses within the greater omentum and supplies the greater curvature of the stomach; forms anastomosis with the right gastroomental artery.
Left gastroomental artery.
Supplies the left portion of the greater curvature and fundus.
Short gastric artery.
Multiple branches that supply the neck, body, and tail of the pancreas.
Pancreatic arteries.
Supplies the posterior region of the stomach.
Posterior gastric artery.
Courses within the lesser omentum and is a major branch off courses to the right of the celiac trunk.
Common hepatic artery.
What are the 3 branches of the common hepatic artery?
Proper hepatic artery, Right gastric artery, and gastroduodenal artery.
Arises from the common hepatic artery within the hepatoduodenal ligament of the lesser omentum, along with the portal vein and common bile duct.
Proper hepatic artery.
Courses within the lesser omentum and supplies the lesser curvature of the stomach; forms anastomosis with the left and right gastric artery.
Right gastric artery.
Descends deep to the first part of the duodenum, giving rise to the right gastroomental (gastroepiploic) artery and the Superior pancreaticoduodenal artery.
Gastroduodenal artery.
What are the two principal branches off the gastroduodenal artery?
Right gastroomental artery and Superior pancreaticoduodenal artery.
The _____ ______ _____ drains nutrient-rich venous blood from the gastrointestinal tract and the spleen to the liver.
The portal venous system.
Formed by the union of the splenic and superior mesenteric veins; collects venous blood from the entire GI tract.
Portal vein.
What are the 3 tributary veins of the foregut from the portal vein?
Right and left gastric veins, Splenic vein and Superior mesenteric vein.
