What are the functions of gastric glands present in the wall of the stomach?

Question

Answer

Gastric glands are present in the walls of the stomach and secrete Gastric juices .The Gastric juice contains three substances:-
1)Hydrochloric acid
2)Pepsin enzyme
3)Mucus

Pepsin Enzyme helps in digestion of proteins and works on in the presence of an Acid i.e.HCl , Hydrochloric acid helps in the functionality of Pepsin and kills any BACTERIA that may have entered along with the food.

Mucus protects the Inner lining of the Stomach from the action of HCL as HCl causes the erosion of inner lining of Stomach.

Answer

The gastric gland system contains an assortment of segment cells and begins at the gastric pit or the opening to the lumen of the stomach.

There are three sorts of gastric organs. Each is recognizable by area and kind of secretion.

1) Pepsinogen: This is found in pepsin and helps in the digestion of protein.

2) Hydrochloric Acid: This is responsible for killing the germs present in the stomach which helps the enzyme by maintaining the acidic nature.

3) Mucous: This acts as a protective layer in the stomach against HCL.

Answer

The gastric gland is the primary secretory unit of the stomach. The gastric gland is an essential body component because it secretes gastric juice and protective mucus. Mucus coats the stomach and helps it dilute enzymes and acids during the digestive process.

Answer

The functions of gastric glands present in the wall of the stomach are:

(a) Production of pepsin enzyme that converts proteins into peptinogens.

(b) Secretion of mucus for protects the wall of stomach.

(c) Secretion of (HCl) Hydrochloric acid kills the germs.

Answer

Walls of Stomach consists gastric glands which Secretes an enzyme Pepsin, Hydrochloric acid and Mucus. Walls of Stomach helps in mixing food through with digestive juice. Hydrochloric acid kills microbes that may enter along with the food and water, it also forms acidic medium for the function of enzyme Pepsin. Pepsin enzyme meant to digest proteins. Mucus protects the walls of the Stomach for the action of acid and enzyme at normal conditions.

Answer

Answer

The glands of the stomach have specialised cells which secrete Hydrochloric acid and enzymes such as pepsin for protein digestion, lipase for fat digestion, hormones such as gastrin and ghrelin . Cells also produce intrinsic factor for vitamin b12 absorption and mucus to protect the stomach from digestive enzymes and acid.

Answer

^^^Gastric glands are present in the wall of the stomach which secrete
(a)gastric juice containing the digestive enzyme like pepsin, renin, mucus and HCl. ...
(b) Secretion of mucus for the protection of innerlining of the stomach.
(c) Secretion of HCl, which kills the bacteria and foreign harmful organisms in the food...

Answer

The gastric glands are the exocrine glands present in the wall of the stomach. These glands secrete gastric juice, which is a mixture of hydrochloric acid, enzymes, and mucus. The gastric juice plays an essential role in the digestion of food.

Functions of Gastric Glands:

1. Secretion of Hydrochloric Acid:
The parietal cells of gastric glands secrete hydrochloric acid, which helps in the breakdown of proteins into peptides. Hydrochloric acid also helps in the activation of pepsinogen, which is a proenzyme secreted by chief cells. The conversion of pepsinogen into pepsin is necessary for the digestion of proteins.

2. Secretion of Pepsinogen:
The chief cells of gastric glands secrete pepsinogen, which is a proenzyme. Pepsinogen is converted into pepsin by hydrochloric acid present in the gastric juice. Pepsin is a proteolytic enzyme that helps in the digestion of proteins into peptides.

3. Secretion of Mucus:
The goblet cells of gastric glands secrete mucus, which protects the stomach lining from the corrosive effects of hydrochloric acid. Mucus also lubricates the food, allowing it to pass through the stomach smoothly.

4. Secretion of Intrinsic Factor:
The parietal cells of gastric glands secrete intrinsic factor, which is necessary for the absorption of vitamin B12. Vitamin B12 is essential for the production of red blood cells.

Conclusion:
In conclusion, the gastric glands present in the wall of the stomach secrete gastric juice, which helps in the digestion of food. The gastric juice contains hydrochloric acid, enzymes, and mucus, which play different roles in the digestion process. The secretion of gastric juice is regulated by various factors such as the nervous system, hormones, and the presence of food in the stomach.
