Where is the stomach located in the body?

The stomach is located in the upper left abdomen, in the left hypochondriac, epigastric, and umbilical regions. It is usually J-shaped but can vary with posture and fullness.

What are the main parts of the stomach?

The stomach has four main parts: the cardia (around the esophageal opening), fundus (dome-shaped area above the cardiac notch), body (central portion), and pyloric part (including antrum, canal, and pylorus).

What structures form the 'stomach bed'?

The stomach bed refers to the posterior surface of the stomach, which is related to structures like the diaphragm, left kidney, left suprarenal gland, pancreas, splenic artery, transverse mesocolon, splenic flexure of the colon, and spleen.

How is the stomach supplied with blood?

The stomach's blood supply comes from arteries like the left and right gastric, gastroepiploic, and short gastric arteries, which are branches of the coeliac trunk. Veins drain into the portal system.

What is the nerve supply to the stomach?

The stomach's nerve supply includes sympathetic nerves from T6–T10 via greater splanchnic nerves and parasympathetic nerves from the vagus nerves, which regulate functions like secretion and motility.

What are some common clinical conditions related to the stomach?

Common stomach-related conditions include gastric carcinoma (often near the pyloric antrum), peptic ulcers (common on the lesser curvature), and vagotomy (surgery to cut the vagus nerve and reduce acid secretion).

What is the function of the stomach?

The stomach stores food, mixes it with gastric juices to form chyme, regulates delivery to the small intestine, destroys bacteria, and helps absorb vitamin B12 via intrinsic factor.
