What does the short gastric artery supply? Short gastric arteries: usually consists of 5-7 arteries that arise to the left of the greater curvature of the stomach. These arteries course through the gastrosplenic ligament of the greater omentum to supply the cardiac orifice and fundus of the stomach .

The right gastric artery supplies the lesser curvature of the stomach . Its branches come off at right angles, in contrast to branches from vagal nerve trunks, which come off obliquely.
Does the gastric artery supply the stomach?
The stomach is supplied by a rich system of arteries derived from the celiac trunk, the first major visceral branch of the abdominal aorta. The lesser curvature of the stomach is supplied by the left and right gastric artery , which are branches of the celiac trunk and the common hepatic artery respectively.
Where does the short gastric arteries come from?
The short gastric arteries are a group of short arteries arising from the terminal splenic artery and the left gastroepiploic artery which supply the fundus of the stomach along it’s greater curvature.
Where does the short gastric vein drain?
The short gastric veins, four or five in number, drain the fundus and left part of the greater curvature of the stomach , and pass between the two layers of the gastrolienal ligament to end in the splenic vein or in one of its large tributaries.
What does right and left gastric artery supply?
The lesser curvature of the stomach is supplied by the left and right gastric arteries, with the latter being a branch of the proper hepatic artery. The greater curvature is supplied by the right and left gastroepiploic arteries, branches of the gastroduodenal and splenic arteries, respectively.
What does the right gastric artery come off of?
The right gastric artery usually originates from the proper hepatic artery, after the origin of the gastroduodenal artery . It is situated in the lesser omentum, accompanied by the same-named vein. The artery runs parallel to the lesser curvature of the stomach where it gives rise to several small branches.
What does the right colic artery supply?
The right colic artery is a branch of the superior mesenteric artery that supplies the ascending colon . It courses to the right towards ascending colon, where it splits into a superior and inferior division.
Which two organs are supplied by the gastroduodenal artery?
The gastroduodenal artery (GDA) is a branch of the common hepatic artery that supplies the pylorus of the stomach, superior part of the duodenum, and the head of the pancreas .
What are the three major arteries that supply the colon?
The major arteries supplying the gastrointestinal tract are the celiac, superior mesenteric, and inferior mesenteric arteries .
Which artery supplies the duodenum and stomach?
In anatomy, the gastroduodenal artery is a small blood vessel in the abdomen. It supplies blood directly to the pylorus (distal part of the stomach) and proximal part of the duodenum.
Does gastric artery supply or drain?
The ascending branches of the left phrenic and left gastric arteries supply the abdominal esophagus and its venous drainage is into the left gastric vein of the portal system . The esophagus has two lymphatic plexus, one in the mucous membrane and the other in the muscular coat.
What artery supplies the esophagus?
The lower thoracic esophagus is nourished by ascending and descending branches stemming from the aorta between the third and fifth intercostal arteries , while the remainder is supplied by dia- phragmatic vessels and branches of the left gastric artery.
What are the short gastric vessels?
The short gastric arteries are a group of short arteries arising from the terminal splenic artery and the left gastroepiploic artery which supply the fundus of the stomach along it’s greater curvature.
What does celiac trunk supply?
The first major branch, which comes off anteriorly at the T12 level, is the celiac trunk. It supplies oxygen-rich blood to the spleen, and structures derived from the embryonic foregut .
What artery supplies the spleen?
Spleen is the hemo-lymph organ, receives its arterial source by splenic artery (SA) . SA is the largest branch of celiac trunk and tortuous in its course.
What are the 4 main veins draining the stomach?
Conventionally the following veins drain into the splenic vein— short gastric, left gastroepiploic, pancreatic, and inferior mesenteric veins . The short gastric veins include four or five veins, which drain the fundus and part of the greater gastric curvature.
What structures are drained by the left gastric vein?
The normal left gastric vein drains both the anterior and posterior surfaces of the stomach , and it ascends the lesser curvature within the lesser omentum to the esophageal hiatus, where it anastomoses with the esophageal veins.
What does the gastric vein drain?
The main function of the left gastric vein is to drain deoxygenated blood from the fundus and upper body of the stomach . Additionally, it anastomoses with the lower esophageal veins and drains the abdominal part of the esophagus.
How many arteries supply the stomach?
The abdominal arteries arise from the abdominal aorta and are comprised of three groups of arteries : unpaired visceral arteries, paired visceral arteries, and parietal arteries.
What artery supplies the antrum of the stomach?
The gastroepiploic artery (GEA) is made up of two arteries which supply the greater omentum and the stomach.
What arteries feed the stomach?
The arterial supply to the stomach is derived primarily from the celiac axis . The celiac axis arises from the proximal abdominal aorta and typically branches into the common hepatic, splenic, and left gastric arteries.
Where does left gastric artery come from?
In human anatomy, the left gastric artery arises from the celiac artery and runs along the superior portion of the lesser curvature of the stomach. Branches also supply the lower esophagus.
What does the middle colic artery supply?
The middle colic artery (from the superior mesenteric) through its right and left branches supplies the right two-thirds of the transverse colon . The inferior mesenteric artery gives off the left colic arteries which supply the left third of the transverse colon and the descending colon.
What artery supplies splenic flexure?
The superior mesenteric artery supplies the midgut from the ampullary region of the second part of the duodenum to the splenic flexure of the large intestine.
Where does the sigmoid artery supply blood to?
The sigmoid arteries provide blood to the lower part of the colon . The specific parts of the colon they supply are the iliac colon, the pelvic colon, and the descending colon. There are always two and sometimes three or four of these arteries located in the colon.
What artery supplies the pancreas?
Pancreas is vascularized by splenic, gastroduodenal and mesenteric superior arteries . The above mentioned blood vessels send numerous branches into the different parts of pancreas and adjacent organs.
What is the largest artery in the body?
How large is the aorta ? The aorta is the largest blood vessel in your body. It’s more than 1 foot long and an inch in diameter at its widest point.
Which arteries supply small and large intestine?
The blood supply to the small and large bowel is derived from the celiac artery and SMA. The celiac axis primarily provides blood flow to the stomach, liver, spleen, and pancreas but is also a source of collateral flow when blood flow in the SMA is reduced.
What is the longest vein in the body?
Did you know that your Great Saphenous Vein is the longest vein in the human body? Extending from the top of your foot to the upper thigh and groin, THIS vein is the major culprit that causes Varicose Veins.
What artery supplies first part of duodenum?
Blood Supply and Lymphatics
The proximal segment of the duodenum is supplied by the gastroduodenal artery and its branches which include the superior pancreaticoduodenal artery.
What is the largest artery to the stomach?
| Abdominal aorta | Segments of the aorta, with both suprarenal and infrarenal abdominal aorta | The abdominal aorta and its branches. | Details | Source Thoracic aorta |

What artery supplies blood to the liver?
The liver receives a blood supply from two sources. The first is the hepatic artery which delivers oxygenated blood from the general circulation. The second is the hepatic portal vein delivering deoxygenated blood from the small intestine containing nutrients.
What vein drains the duodenum?
Duodenum. The duodenal veins drain directly from the duodenum into the pancreaticoduodenal veins . From here they merge back into the two largest vessels which are the superior mesenteric vein and the common hepatic vein.
