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.

What are the similarities and differences between parietal cells and chief cells in the wall of the stomach?
both cell produce gastric juice to digest the food
Do parietal cells have a cell membrane?
Yes, parietal cells (like all cells) have a cell membrane. Parietal cells have a huge surface area (their membrane has deep folds called canaliculi).
What cells are found in the gastric glands?
I would say chief cells since they secrete pesinogen whereas parietal cells secrete HCl which tecnically aids in chemical digestion but has other functions as welll. Obviously, HCl alone is not enough to perform chemical digestion which is why more complex molecules such as pesinogen which is converted to pepsin is produced.
What other cells work with the parietal cell?
Mast cells and EC (enterochromaffin) cells produce histamine, which stimulates the parietal cell to produce hydrochloric acid.
How are chief cells activated?
Gastric chief cells (as opposed to the chief cells present in the parathyroid gland) are the zymogen cells in the stomach that release pepsinogen (a precursor (zymogen) of pepsin). Without stimulation chief cells normally secrete pepsinogen at about 20% of the maximum ability. ACh (released by nerves) is the most important pathway for gastric chief cell activation. ACh also stimulates parietal cells, which secrete HCl (stomach acid). The fall in pH causes a reflex which further stimulates chief cells. Alternatively, acid in the duodenum (the first portion of the small intestine), stimulates release of secretin from S cells of the small and large intestine. Secretin also activates gastric chief cells.
What do parietal cells and chief cells produce together?
Parietal cells produce cover cells and chief cells produce micro and megaspores
Which kind of cell produces hydrochloric acid in the stomach?
Osteoclast (most likely from my point of view)
The parietal cells in this organ produce hydrochloric acid?
stomach
What cells in the stomach function to form enzymes and acids?
Parietal cells and chief cells
Parietal cells are found in gastric mucosa and secretes hydrochloric acid in stomach. They are also known as Chief cells or oxyntic cells.?
Parietal cells (or oxyntic cells) are epithelium cells found in the gastric mucosa, they secrete hydrochloric acid (HCl) and intrinsic factor (which is required for vitamin B12 absorption). Chief cells are not the same as parietal cells. Chief cells secrete pepsinogen and rennin.
What are the secretions of the chief cells and parietal calls?
digestive enzyms and hydrochloric acid
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.
Which digestive system organ is the target of gastrin?
Parietal cells in the stomach, which secrete HCl
What cells produce hydrocholoric acid in stomach?
Parietal cells
What cells produce pepsinogen and hcl?
Chief cells of the stomach (gastric glands in stomach have chief cells)
What are the similarities and differences between parietal cells and chief cells in the wall of the stomach?
both cell produce gastric juice to digest the food
What are the types of secretory cells in the stomach and what do they secrete?
Gastric glands which secrete:HClRenninpepsin
