Pyloric Part

The pylorus is the region of the stomach that connects to the duodenum. It is divided in two parts: the pyloric antrum, which connects to the body of the stomach. the pyloric canal, which connects to the duodenum.

Lesser Curvature

The lesser curvature of the stomach, extending between the cardiac and pyloric orifices, forms the right or posterior border of the stomach.

Esophagus

The part of the alimentary canal that connects the throat to the stomach; the gullet. In humans and other vertebrates it is a muscular tube lined with mucous membrane.

Cardia

The upper opening of the stomach, where the esophagus enters.

Fundus

The upper part of the stomach, which forms a bulge higher than the opening of the esophagus.

Greater Curvature

The greater curvature of the stomach is directed mainly forward, and is four or five times as long as the lesser curvature.

Body Of Stomach

Large central portion of the stomach.

Duodenum

The first part of the small intestine immediately beyond the stomach, leading to the jejunum.

Ascending Colon

The first main part of the large intestine, which passes upward from the cecum on the right side of the abdomen.

Cecum

The cavity in which the large intestine begins and into which the ileum opens.

Jejunum

The part of the small intestine between the duodenum and ileum.

ileum

Last part of small intestines, absorbs enzymes and anything left over by jejunum.

Bile Duct

The duct that conveys bile from the liver and the gallbladder to the duodenum.

Pyloric Gland Region

Glands are branched, coiled tubular glands, shorter than other gastric glands. Gastric pits are deeper. Forms the pyloric sphincter.

Cardiac Gland Region

The cardiac glands of the stomach secrete primarily mucus. They are few in number and occur close to the cardiac orifice where the esophagus joins the stomach.

Pancreatic Ducts

The pancreatic duct, is a duct joining the pancreas to the common bile duct to supply pancreatic juices which aid in digestion provided by the "exocrine pancreas".

Minor Duodenal Papilla

The minor duodenal papilla is the opening of the accessory pancreatic duct into the duodenum. It is sometimes absent, and often nonfunctional.
