the stomach
The organ structure rugae can be found in a number of anatomical structures in the body.
It controls the function of the muscles of the wall of the stomach and the muscular sphincter. Also, the nervous tissue controls the secretory function of the stomach.
Found in the stomach
They secrete Hydrochloric acid in the stomach to help break down peptides.
The stomach has simple columnar epithelium primarily for its protective and secretory functions. This type of epithelium facilitates the secretion of mucus, which protects the stomach lining from the harsh acidic environment and digestive enzymes. Additionally, the columnar structure allows for efficient absorption and transport of nutrients and substances. Overall, the simple columnar epithelium is well-suited to the stomach's specialized roles in digestion and protection.
Hydrochloric acid is secreted by the parietal cells in the stomach lining. These cells are responsible for producing the acidic environment in the stomach that aids in digestion.
A secretory vacuole is a membrane-bound organelle found in certain cells, such as plant and fungal cells, that is involved in the storage and secretion of various substances such as proteins, enzymes, and pigments. When needed, these vacuoles release their contents outside of the cell through exocytosis.
The parietal cells of the stomach secrete hydrogen ions and chloride ions, which combine to form hydrochloric acid.
Examples of secretory proteins are collagen, insulin, and digestive enzymes of the stomach and intestine.
