Gastric Anatomy

The stomach has four main anatomical divisions. These are the openings of gastric pits which extend into the mucosa as straight and branched tubules forming gastric glands.

The cells in the stomachs lining will excrete a strong acidic mixture of hydrochloric acid sodium chloride and potassium chloride.

Gastric anatomy. A gastric band may be placed around the cardia area which can adjust to limit intake. The role of this mucus is not currently known. The cardia fundus body and pylorus.

Chief cells and parietal cells are in the deeper parts of the glands. The image above shows rugae on the surface of a dogs stomach. The chief cells secrete digestive enzymes and the parietal cells release a solution containing hydrochloric acid.

Fundus the rounded often gas filled portion superior to and left of the cardia. If the lining of the stomach is examined with a hand lens one can see that it is covered with numerous small holes. The innermost lining of the stomach wall is mucosa which consists of columnar epithelium lamina propria and muscularis mucosa.

During an endoscopy a doctor can take. Inner oblique unique to stomach. The abdomen contains all the digestive organs including the stomach.

Mucous neck cells gastric glands in the upper part of the stomach contain mucous neck cells that secrete thin acidic mucus that is much different from the mucus secreted by the goblet cells of the surface epithelium. The anatomy of the stomach may be modified or the stomach may be bypassed entirely. A test of how rapidly food passes through the stomach.

Surgical removal of the stomach is called a gastrectomy and removal of the cardia area is a called a cardiectomy. The stomachs main tool for digestion is the powerful mix of secretions collectively called gastric juices. This gastric acid or colloquially known as gastric juice will work to break down the bonds within the food particles at the molecular level.

Cardia surrounds the superior opening of the stomach at the t11 level. The diaphragm forms the upper surface of the abdomen. Submucosa contains a rich network of blood vessels and meissners nerve plexus.

Gastric glands generally contain three types of secretory cells. The smooth muscles of the stomach are arranged in 3 layers. The food is labeled with a chemical and viewed on a scanner.

To counteract these strong juices the stomach protects itself with mucus like secretions. Mucous cells in the necks of the glands near the openings of the gastric pits secrete mucus. Anatomy of the stomach.
