Describe the anterior and posterior anatomical relations of the stomach
![](https://s3.amazonaws.com/brainscape-prod/system/cm/327/947/745/q_image_thumb.png?1510331983)
- Anterior: greater omentum, abdominal wall, left lobe of liver, gall bladder

Where can the arterial supply of the stomach be derived from?
Coeliac trunk and its branches
Describe the blood supply to the lesser and greater curvatures of the stomach
- Lesser curvature: anastomoses by the right and left gastric arteries
- Greater curvature: anastomoses by the right and left gastro-omental arteries

Where do the right and left gastric arteries arise from?
- Right gastric – branch of the common hepatic artery, which arises from the coeliac trunk
- Left gastric – arises directly from the coeliac trunk

Where do the right and left gastro-omental arteries arise from?
- Right gastro-omental – terminal branch of the gastroduodenal artery, which arises from the common hepatic artery
- Left gastro-omental – branch of the splenic artery, which arises from the coeliac trunk

The veins of the stomach run parallel to the arteries.
Describe the venous drainage of the of the stomach
- Lesser curvature: right and left gastric veins
- Greater curvature: right and left gastro-omental veins
- Fundus: short gastric veins
Where do the right and left gastric veins drain?
The right and left gastric veins drain into the hepatic portal vein

Where does the short gastric vein, right and left gastro-omental veins drain into?
The short gastric vein, left and right gastro-omental veins ultimately drain into the superior mesenteric vein

What is the coeliac trunk and what does it do?
- The coeliac trunk is a major artery of the abdomen
- It arises from the abdominal aorta, and supplies many of the gastrointestinal viscera

What are the main branches of the coeliac trunk?

The greater and lesser omenta divide the abdominal cavity into two; the greater and lesser sac.
Describe the entrance into the lesser sac
The greater and lesser sacs communicate via the epiploic foramen, a hole in the lesser omentum
