Stomach Anatomy and Structure

The stomach is located in the left Hypochondrium, Umbilical, and Epigastrium regions of the abdomen.

The stomach can hold approximately 2-3 liters of food.

In obese people, the stomach often takes on a 'steer horn' shape.

The cardiac end of the stomach is located behind the 7th left costal cartilage.

A physiological sphincter is present at the cardiac end of the stomach.

The Epiploic Foramen allows the stomach to expand.

The free margin of the lesser omentum contains the right and left gastric arteries and the portal vein.

The gastrosplenic and lienorenal ligaments form the upper part of the stomach bed.

The lower part of the greater curvature of the stomach forms the lower border of the lesser sac.

A hernia that can occur in the lesser sac through the Epiploic Foramen.

The Greater Omentum has 3 layers.

The gastrosplenic ligament attaches to the convex left border of the stomach.

The posterior wall of the stomach adheres to the posterior wall of the lesser sac in the intermediate part of the stomach.

The prepyloric vein indicates the position of the pyloric orifice.

The right gastric vein drains into both the portal and superior mesenteric vein.

Lymph from the pylorus drains into all of the above.

The cavity of the greater sac separates the stomach from the spleen.

The greater anterior gastric nerve supplies the fundus and body of the stomach.

A small bare area close to the cardiac orifice of the stomach is not covered by peritoneum.

Lymphatic drainage from the upper left quadrant goes to the pancreaticosplenic lymph nodes.
