What are the major lower abdominal blood vessels?
The blood supply to all the organs in the abdomen that we’ve seen so far, the GI tract, the liver, pancreas and spleen, comes from three midline branches of the abdominal aorta. These are the celiac, the superior mesenteric and the inferior mesenteric arteries.
What are the major vessels of the abdomen?
Three major arterial anastomoses of the abdomen exist. The first is between the celiac trunk and the superior mesenteric artery via the pancreaticoduodenal arteries. The second exists between superior and inferior mesenteric arteries via the middle and left colic arteries.
What are the main veins of the abdomen and pelvis?
The two principal venous tributaries in the pelvis are the internal and external iliac veins, while the gastric veins dominate the abdomen.
What are the 3 midline arteries that supply the organs of the abdomen?
The three midline branches are the celiac trunk, the superior mesenteric, and the inferior mesenteric.
What is the main artery in the stomach called?
The superior mesenteric artery is in the midsection of the digestive tract (midgut). It originates from the aorta between the celiac artery and renal arteries. The celiac artery supplies blood to the liver, spleen and stomach.
What is posterior to the stomach?
The posterior surface of the stomach is related to the left hemidiaphragm, the spleen, the left kidney (and adrenal), and the pancreas (stomach bed).
What main vessels form systemic venous circulation in abdomen?
In the lower abdomen, the aorta bifurcates into the left and right common iliac arteries, which supply blood to the pelvic region and the legs via additional bifurcations and branches….Vascular Network.

Where are the large veins in the abdomen?
Two large veins from above: the superior epigastric (medial) and musculophrenic (lateral) Two large veins from below: the inferior epigastric and the deep circumflex iliac. Small tributaries of the intercostal, subcostal and lumbar veins, which accompany the corresponding arteries.
Where is the main vein in your stomach?
The gastric veins are similar in position to the arteries along the lesser and greater curvatures. These veins drain either directly or indirectly into the portal system. The left gastric vein runs to the left along the lesser curvature, receiving the esophageal veins below the esophageal hiatus in the diaphragm.
What supplies blood to the abdominal wall?
The superior and inferior epigastric arteries provide a rich arcade arising from the internal thoracic artery superiorly and the external iliac artery inferiorly. The musculophrenic artery, deep circumflex iliac artery, and subcostal arteries supply the lateral abdominal wall.
What causes enlarged blood vessels in the stomach?
Esophageal varices are abnormal, enlarged veins in the tube that connects the throat and stomach (esophagus). This condition occurs most often in people with serious liver diseases. Esophageal varices develop when normal blood flow to the liver is blocked by a clot or scar tissue in the liver.

What are the branches of the abdominal aorta?
It supplies the mediastinum, bronchi, esophagus, pericardium, and thoracic surface of the diaphragm with its arterial branches. The abdomen is supplied by the branches of the abdominal aorta: celiac trunk, renal artery, gonadal artery, mesenteric arteries, and common iliac arteries.
Which vessels supply blood to the small intestine?
Vessels of the small intestine are grouped by which segment they supply: The duodenum is supplied by the superior and inferior pancreaticoduodenal arteries, which are the branches of the gastroduodenal and superior mesenteric arteries, respectively.
