What else can I help you with?
What are the types of secretory cells in the stomach and what do they secrete?
Gastric glands which secrete:HClRenninpepsin
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.
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)
Gastrin secretes what?
pepsinogen (a precursor of pepsin) which helps humans digest, when activated by HCL.
What role do cells play preventing the stomach from digesting itself?
Epithelial cells lining the inside stomach secrete a substance which prevents the stomach acid harming the lining of the stomach.
What cells produce pepsinogen and hcl?
Chief cells of the stomach (gastric glands in stomach have chief cells)
Which cells secret HCl in stomach?
Chief cells in the stomach secrete HCl, along with pepsinogen, which is then converted to pepsin when exposed to the acidic environment. This acid helps to break down food and kill bacteria in the stomach.
What produces HCI and pepsinogen?
Hydrochloric acid (HCl) is produced by parietal cells in the stomach, while pepsinogen is produced by chief cells in the stomach. Together, HCl and pepsinogen play important roles in the chemical digestion of food in the stomach.
What secrete hydrochloric acid into the stomach?
The presence of food may trigger release of gastric acid, which is the hydrochloric acid. This in turn activates the inactive protein pepsinogen into pepsin.
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.
Which cells secrete Pepsin?
Chief cells in the stomach secrete pepsinogen, which is then activated to pepsin by hydrochloric acid present in the gastric juice. Pepsin is an enzyme that breaks down proteins into smaller peptides during the process of digestion.
Are Chief cells found in the basal regions of the gastric glands?
No, chief cells are found primarily in the middle regions of the gastric glands in the stomach. They secrete pepsinogen, which is a precursor to the enzyme pepsin that helps with protein digestion.
