The chief cells secret pepsinogen and gastric lipase. The activated form of pepsinogen (i.e. pepsin) can break down proteins into peptides. As for the lipase, it can split trigylcerides into fatty acids and monoglycerides.

What cells produce pepsinogen and hcl?
Chief cells of the stomach (gastric glands in stomach have chief cells)
What cells in the stomach function to form enzymes and acids?
Parietal cells and chief cells
What type of cells in the epithelial layer of stomach secrete pepsinogen?
Zymogenic, or chief, cells.
Which kind of cell produces hydrochloric acid in the stomach?
Osteoclast (most likely from my point of view)
What is the main function of stomach lining cells?
Gastric gland cell types:1-Goblet Cells - produce mucus and secrete it into the lumen (open space) of the stomach2-Parietal Cells- secrete HCl (Hydrochloride acid)3- Chief Cells secrete pepsinogen the inactive form of pepsin. It is self digested and forms pepsin in the acid environment of the stomach.4-Argentaffin Cells- serotonin and histamine maintain structure of gastric mucosa.5-G-cells- secrete gastrin a hormone that regulate rate of digestion.
What are the types of secretory cells in the stomach and what do they secrete?
Gastric glands which secrete:HClRenninpepsin
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 organ has chief and parietal cells?
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 cells secrete hydrochloric acid?
Chief cells lining the stomach. (They actually secrete H+ and Cl- ions individually, but it becomes HCl in the solution).
Does the stomach contain hormone producing cells?
"Glands" are like tiny pits in the lining of the stomach. These glands are lined with certain cells: Parietal cells: secrete acid and intrinsic factor Mucous cells: secrete mucus Chief cells: secrete pepsinogen Enteroendocrine cells: secrete various Stem cells: create new cells (So glands are not cells)
Are there cells that hold digestive juices?
The cells that hold digestive juices are called the gastric chief cells. These are located in the stomach that secretes enzymes for protein breakdown.
Which type of cell in the stomach secretes pepsinogen?
After a biopsy, bowel tissue was found in my stomach. What does this mean?
