|
|
Left gastric artery
|
-branch of celiac trunk
-descends and comes down along lesser curvature of stomach |
|
|
Splenic Artery
|
-branch of celiac trunk
-larger artery that traverses laterally, posterior to the stomach, superior to pancreas -ultimately supplies the spleen -extends short gastric branches to supply superior part of stomach -gives off the left gastroomental/gastroepiploic artery |
|
|
Left gastroomenta/gastroepiploic artery
|
-branch of the splenic artery
-supplies the greater curvature of the stomach in part |
|
|
Common Hepatic Artery
|
-branch of celiac trunk
-divides into hepatic artery proper and gastroduodenal artery - |
|
|
Gastroduodenal artery
|
-supraduodenal portion supplies blood to superior portion of duodenum
-then gives off anterior and posterior superior pancreaticoduodenal arteries |
|
|
Anterior and posterior pancreaticoduodenal arteries
|
-branches of gastroduodenal artery
-contribute to right blood supply of head of pancreas |
|
|
What portion(s) of the gut is the pancreas derived from?
|
-foregut
-midgut |
|
|
Hepatic Artery Proper
|
-ascends within the hepatoduodenal ligament
-divides into right and left hepatic arteries -middle/intermediate branch may also exist |
|
|
What two branches does the gastroduodenal artery give off after it gives off the supraduodenal portion?
|
-anterior superior pancreaticoduodenal artery
-posterior superior pancreaticoduodenal artery |
|
|
What artery supplies the gallbladder?
|
-Cystic artery
|
|
|
where does the cystic artery branch from?
|
-Hepatic artery proper
|
|
|
what other artery also branches from the hepatic artery proper?
|
-right gastric artery
|
|
|
Right gastric artery
|
-comes off hepatic artery proper
-descends down lesser curvature of stomach -anastamoses with left gastric artery |
|
|
The splenic artery gives off two branches along the body and tail of the pancreas. What are they?
|
-Inferior pancreatic artery
-Dorsal pancreatic artery |
|
|
What does the gastroduodenal artery branch into at the head of the pancreas?
|
-anterior and posterior superior pancreaticoduodenal arteries
|
|
|

|
-hepatic portal vein
|
|
|
What do the right and left gastroepiploic/gastroomental veins terminate into?
|
-superior mesenteric vein
|
|
|
Where do the spleinic vein, inferior and superior mesenteric veins join and empty into?
|
-hepatic portal vein
|
|
|
true or false: all venous drainage from abdominal viscera passes through the liver
|
TRUE
|
|
|
What do the right and left hepatic veins empty into?
|
IVC
|
|
|
what two branches form the inferior pancreatic artery?
|
-dorsal pancreatic artery
-greater pancreatic artery |
|
|
What three veins come together to form the hepatic portal vein and drain the foregut?
|
-Splenic vein
-Inferior mesenteric vein -Superior mesenteric vein |
|
|
Are the arcades straighter in the ileum or jejunum?
|
Jejunum
|
|
|
Superior Mesenteric Artery
|
-supplies small intestine and part of colon
-arises from abdominal aorta -runs in root of mesentery to ileocecal junction -sends many branches to jejunum and ileum -runs between the layers of mesentery |
|
|
Branches of SMA

|
|
Middle colic artery
|
-branch of SMA

|
|
Right colic artery
|
-branch of SMA
-passes retroperitoneally to reach ascending colon, which it supplies |
|
|
Ileocolic artery
|
-terminal branch of SMA
-runs along root of mesentery and divides into ileal and colic branches -supplies ileum, cecum, and ascending colon |
|
|
What two arteries anastamose to form a marginal artery?
|

|
|
What does the marginal artery anastamose with and where?
|
-IMA
