What are 3 cell types found in the digestive system?

function in digestive system …of three major cell types: zymogenic, parietal, and mucous neck cells. At the base of the gland are the zymogenic (chief) cells, which are thought to produce the enzymes pepsin and rennin. (Pepsin digests proteins, and rennin curdles milk.)

What type of cell are the cells in your gut?

Four major types of secretory epithelial cells cover the surface of the stomach and extend down into gastric pits and glands: Mucous cells: secrete an alkaline mucus that protects the epithelium against shear stress and acid. Parietal cells: secrete hydrochloric acid. Chief cells: secrete pepsin, a proteolytic enzyme.

Which is the digestive bag of cell?

The lysosomes are known as digestive bags or suicidal bags or recycling centers or scavengers of cells because of the following properties: -The lysosomal vesicles contain almost 40 different types of hydrolases, for example, lipases, carbohydrases, proteases, etc.

What is the gastric pit?

The Stomach Secretes HCl, Pepsinogen, Mucus, Gastric Lipase, and Intrinsic Factor. The lining of the stomach at rest is thrown into thick, velvety folds called rugae. These contain microscopic invaginations, called gastric pits, that each open into four or five gastric glands.

What type of cells line the stomach?

The mucosal lining of the stomach is simple columnar epithelium with numerous tubular gastric glands. The gastric glands open to the surface of the mucosa through tiny holes called gastric pits. Four different types of cells make up the gastric glands: Mucous cells.

Why lysosomes are called digestive bag?

They are called the ‘digestive bags’ because they have enzymes that play a major role in cellular digestion. It will mix with a food vacuole and the enzymes in the lysosome help in digesting the food materials in the food vacuole.

What is the purpose of gastric pits?

Foveolae or gastric pits communicate with the lumen of the stomach and transport gastric cell secretions. The glandular stomach functions in the enzymatic and hydrolytic digestion of ingested food substances.

What are the 3 parts of the stomach?

Regions of the stomach

  • The cardia is the first part of the stomach below the esophagus.
  • The fundus is the rounded area that lies to the left of the cardia and below the diaphragm.
  • The body is the largest and main part of the stomach.
  • The antrum is the lower part of the stomach.

What is the most powerful digestive chemical in the stomach?

Pepsin, the powerful enzyme in gastric juice that digests proteins such as those in meat, eggs, seeds, or dairy products. Pepsin is the mature active form of the zymogen (inactive protein) pepsinogen. Pepsin was first recognized in 1836 by the German physiologist Theodor Schwann.

What are the folds in the stomach lining called?

Ménétrier’s disease causes the ridges along the inside of the stomach wall—called rugae—to enlarge, forming giant folds in the stomach lining. The rugae enlarge because of an overgrowth of mucous cells in the stomach wall.
