Howdy, iam Cecil Stillings, Don’t work too hard.
Hey there! You may have heard of parietal cells and chief cells, but do you know the difference between them? Well, let me tell ya - they’re actually quite different. Parietal cells are found in the stomach and produce hydrochloric acid, while chief cells are also found in the stomach and secrete pepsinogen. Whoa! Talk about two totally different functions. So there you have it - that’s the difference between parietal and chief cells in a nutshell.
What Is The Difference Between Parietal Cells And Chief Cells? [Solved]
Well, parietal cells and chief cells are the two main types of exocrine secretory cells in the stomach. Parietal cells pump out hydrochloric acid, while chief cells produce digestive enzymes and pepsin. So, they both play a key role in digestion.
Location: Parietal cells are located in the stomach, while chief cells are located in the small intestine.
Function: Parietal cells secrete hydrochloric acid and intrinsic factor, which helps with digestion and absorption of vitamin B12, respectively. Chief cells secrete pepsinogen, an enzyme that breaks down proteins into smaller peptides for digestion.
Structure: Parietal cells have a large central nucleus surrounded by cytoplasm filled with secretory granules containing hydrochloric acid and intrinsic factor; chief cells have a single nucleus surrounded by cytoplasm filled with secretory granules containing pepsinogen.
Appearance: Parietal cells appear as large cuboidal or columnar shaped epithelial cells; chief cells appear as small cuboidal or columnar shaped epithelial cells with a single nucleus at the center of each cell body.
Parietal cells are a type of cell found in the stomach lining, and their chief function is to produce hydrochloric acid. This acid helps break down food so that it can be digested more easily. So, while parietal cells and chief cells both exist in the stomach, they have different roles: parietal cells make acid, while chief cells secrete digestive enzymes.
