Which is feature provides protection for the interior surface of the stomach?

Which is feature provides protection for the interior surface of the stomach?

The stomach mucosa contains numerous shallow depressions called ________. Which feature provides protection for the interior surface of the stomach against the acids and enzymes in the gastric lumen? Parietal cells, chief cells, and G cells are major components of which structure? Parietal cells secrete hydrochloric acid and ________.

What protects the stomach from its own acid?

Bicarbonate is alkaline, a base, and neutralizes the acid secreted by the parietal cells, producing water in the process. This continuous supply of bicarbonate is the main way that your stomach protects itself from autodigestion (the stomach digesting itself) and the overall acidic environment.

How does the stomach protect itself from autodigestion?

This continuous supply of bicarbonate is the main way that your stomach protects itself from autodigestion (the stomach digesting itself) and the overall acidic environment. In some individuals, due to impairments in blood supply to the stomach, or to overproduction of acid, this defense system does not work as well as it should.

Which is part of the digestive system secretes mucus?

Digestive system. Gastric glands are composed of epithelial cells (B), chief cells (D), and parietal cells (E). The chief and parietal cells produce and secrete mucus (F) to protect the lining of the stomach (C) against the harsh pH of stomach acid. The mucus is basic, while the stomach acid (A) is acidic.

How does the stomach protect itself from acid?

The stomach is protected by the epithelial cells, which produce and secrete a bicarbonate-rich solution that coats the mucosa. Bicarbonate is alkaline, a base, and neutralizes the acid secreted by the parietal cells, producing water in the process.

How is the mucosal lining of the stomach protected?

The barrier is a layer of thick mucus secreted together with an alkaline fluid. Since the mucus is a gel, it entraps the alkaline fluid so that the stomach is coated. Sucralfate, a polymer of sucrose with aluminum hydroxide, forms a protective coating on the mucosal lining, particularly in ulcerated areas.

Which is part of stomach secretes hydrochloride acid?

The gastric glands (one gland is shown enlarged on the right) contain different types of cells that secrete a variety of enzymes, including hydrochloride acid, which activates the protein-digesting enzyme pepsin. The stomach mucosa’s epithelial lining consists only of surface mucus cells, which secrete a protective coat of alkaline mucus.

Which is the most important part of the digestive system?

HCL since living cells of the stomach and everywhere are largely protein , it is amazing that they are not digested by the activity of stomach enzymes. the most important means of stomach protection is the __________ it produces. mucus a milk protein digestion enzyme found in children but uncommon in adults is _____
