When these parietal cells shrink in size (atrophy), they produce less and less intrinsic factor
Parietal cells
cells shrink because salt water is hypertonic solution.
Yes, parietal cells (like all cells) have a cell membrane. Parietal cells have a huge surface area (their membrane has deep folds called canaliculi).
Osteoclast (most likely from my point of view)
The cells in the zucchini shrink because they lose their water
Parietal cells are found in the fundic zone of the stomach.
Chief cells in the stomach work with parietal cells to produce gastric acid. Chief cells secrete pepsinogen, which is activated by the acid produced by parietal cells to form pepsin, an enzyme that helps break down proteins. Together, parietal and chief cells contribute to the digestive process in the stomach.
Chief and parietal cells are found in the fundic zone of the stomach.Chief cells produce pepsinogen, and parietal cells produce hydrochloric acid. Both of these products assist in the chemical breakdown of stomach contents.
Parietal cells are found in the fundic zone of the stomach.
No, pepsinogens are not produced by parietal cells; they are produced by chief cells in the stomach. Parietal cells are responsible for secreting hydrochloric acid and intrinsic factor. Pepsinogens are inactive precursors of pepsin, an enzyme that aids in protein digestion, and they are activated into pepsin in the acidic environment created by the hydrochloric acid from parietal cells.
Parietal cells are acidophilic because they contain a large number of mitochondria. The mitochondria, which are needed to pump hydrogen ions against their concentration gradient, are acidophilic; therefore, parietal cells are acidophilic as well.
