After a biopsy, bowel tissue was found in my stomach. What does this mean?
one of the cells in your body is a beta cell
chief cells
Gastric chief cells are in the digestive system. They release pepsinogen which is a digestive enzyme that when activated by hydrochloric acid turns into pepsin and helps in the digestion of proteins. Chief cells may also refer to parathyroid chief cells which produce and secrete parathyroid hormone when stimulated by low levels of calcium.
Zymogenic, or chief, cells.
G cells
The stomach primarily secretes the enzyme pepsin, which is a type of protease, which breaks down proteins.
The alpha cells of the pancreas are the source of release glucagon.
Rugai is the tissue that protects from the harsh acids of the stomach. The innermost layer is called Simple Columnar Epithelium. This type of tissue provides the most surface area for absorption and secretion. Parietal cells secrete HCl and pepsinogen.
Proteins are digested in your stomach. Pepsinogen is secreted by the chief cells. Pepsinogen is converted to pepsin by hydrochloric acid. This pepsin brakes the peptide bond of proteins to form polypeptides.
The juice secreted by the stomach lining is called gastric juice. ("Gastric" just means "stomach".)It is strongly acidic, with a pH of about 2. The acidity is contributed by hydrochloric acid (which is released at a pH of about 1) secreted by parietal (= oxyntic cells) in the stomach epithelium (inner lining).The juice also contains pepsinogen (a precursor of the enzyme pepsin, which digests proteins) and rennin, which facilitates the digestion of lipids; these are produced by chief cells.The stomach epithelium also secretes mucus (from mucous cells) to protect the stomach itself both physically and chemically.
Apocrine sweat gland
