The gastric gland is the gland present in the stomach.
Understanding Gastric Glands
Gastric glands are essential structures found within the lining of the stomach. These glands play a vital role in digestion by producing various substances. Let's explore their significance:
Role of Gastric Glands
-
Secretion of Gastric Juice: The primary function of gastric glands is to secrete gastric juice. This complex fluid contains:
- Hydrochloric Acid (HCl): Aids in breaking down food and killing bacteria.
- Pepsinogen: An inactive enzyme that is converted to pepsin, a protein-digesting enzyme.
- Intrinsic Factor: Crucial for the absorption of vitamin B12.
-
Protective Mucus: Gastric glands also produce protective mucus that lines the stomach walls. This mucus acts as a barrier against the corrosive effects of stomach acid, preventing self-digestion of the stomach lining.
-
Location: According to the reference, gastric glands are branched tubules found in the inner lining of the stomach.

| Feature | Description |
|---|---|
| Shape | Branched tubules |
| Location | Inner lining of the stomach |
| Function | Secrete gastric juice and protective mucus |
In summary
- The gastric gland is located in the stomach.
- It is responsible for producing gastric juice which includes hydrochloric acid, pepsinogen and intrinsic factor.
- The gastric gland also produces protective mucus.
