What is the only part of the digestive tract that drains directly into the IVC?
What are the first branches of the abdominal aorta as it descends through the diaphragm?
-Right inferior phrenic artery
-Left inferior phrenic artery
What do the right and left inferior phrenic arteries supply?
-the inferior surface of the diaphragm
Celiac Trunk
-distal to inferior phrenic arteries
-it and its branches supply the foregut
consists of:
consists of:
-small intestine
-ascending colon
-transverse colon
consists of:
-descending colon
-sigmoid colon
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?
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
Where do the right and left gastric veins empty into?
-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
What do the right and left hepatic veins empty into?
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?
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
-Right colic
Middle colic artery
-branch of SMA
-ascends retroperitoneally and passes between layers of transverse mesocolon
-supplies transverse colon
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?
-middle colic
-right colic
What does the marginal artery anastamose with and where?
-near left colic flexure
What does the Inferior Mesenteric Artery supply?
-descending colon
-sigmoid colon
-(all of hindgut)
Branches of IMA
-Left colic artery (ascending and descending branches)
-Sigmoid arteries
-Superior rectal artery
