What are the types of secretory cells in the stomach and what do they secrete?
Gastric glands which secrete:HClRenninpepsin
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)
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 cells secrete hydrochloric acid?
Chief cells lining the stomach. (They actually secrete H+ and Cl- ions individually, but it becomes HCl in the solution).
Why don't protease digest stomach and small intestine?
The protease released in the stomach is pepsin. When it is released it's in an inactive form called pepsinogen. Hydrochloric acid (HCL) is also released. HCL actives the pepsinogen to pepsin so it can break down protein. Both HCL and pepsinogen are released from different cells in the glands so they don't combine until they are released into the stomach, this prevents them from eating away the stomach wall. ALSO the stomach secretes a coating of mucus from epithelial cells which helps protect the stomach lining from being digested by pepsin and HCL.
What are Wine glass shaped cells that secrete mucus?
The Wine glass shaped cells that secrete mucus are called "goblet cells". These are simple columnar epithelial cells found scattered among the epithelial linings of intestine and respiratory tract.
Pepsinogen is the precursor to the gastric enzyme for protein digestion and is secreted by the parietal cells?
it is secreted by stomach glands as an inactive proenzyme, pepsinogen, which is converted to pepsin by the cleavage of acid-labile linkages in the acidic (low pH) environment of the stomach.
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 tissues make up a cat's stomach?
Rugai is the tissue that protects from the harsh acids of the stomach. The innermost layer is called Simple Columnar Epithelium. This type of tissue provides the most surface area for absorption and secretion. Parietal cells secrete HCl and pepsinogen.
