What is the function of the chief cells of the parathyroid?
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.
What type of cells in the epithelial layer of stomach secrete pepsinogen?
Zymogenic, or chief, cells.
What cell type secretes gastrin?
G cells in the stomach lining secrete gastrin hormone. This hormone helps in the regulation of gastric acid secretion and motility in the stomach.
What main enzyme does the stomach secrete?
The stomach primarily secretes the enzyme pepsin, which is a type of protease, which breaks down proteins.
What tissues make up a cat's stomach?
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.
Name each different type of gastric gland and the products that they produce?
cell-->secretion-->function: 1)mucus cell-->goblet cells-->acidic mucus, 2)chief cell-->pepsinogen-->protein digesting enzyme, 3) parietal cell-->HCl and intinsic factor-->provides surface area, and 4) G cell-->gastrin(hormone)-->regulates stomach secretion.
What type of juice of found in the stomach?
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.
Which cell type found in connective tissue proper and close to blood vessels secretes heparin and histamine?
The cell type found in connective tissue proper that is close to blood vessels and secretes heparin and histamine is called a mast cell. Mast cells play a crucial role in the immune response and are involved in inflammatory processes. Heparin acts as an anticoagulant, while histamine is involved in promoting blood flow and increasing vascular permeability during allergic reactions.
What type of gland secretes earwax?
Apocrine sweat gland
The type of cell junction that prevents the contents of the stomach or urinary bladder from leaking into surrounding tissues is the?
Tight Junctions
What stomach contains epithelial and what other type of tissue?
The stomach contains epithelial tissue, specifically simple columnar epithelium, which lines the stomach and secretes mucus and gastric juices. In addition to epithelial tissue, the stomach also contains smooth muscle tissue, which is responsible for the involuntary contractions that help mix and propel food through the digestive tract. Together, these tissues play crucial roles in digestion and the overall functioning of the stomach.
Type of hormone secreting cell that secretes glucagon?
The alpha cells of the pancreas are the source of release glucagon.
