Question

What types of cells are found in gastric glands and what do they secrete?

Answer 1

Hint: Digestive juices, which contain enzymes for food digestion, are secreted by the digestive glands. The digestive system also includes associated glands such as the pancreas, liver, and others that secrete secretions into the alimentary canal to aid digestion.

Complete answer:
The gastric glands are distributed throughout the stomach. The fundic glands, cardiac glands, and pyloric glands are the three glands that make up the stomach. The stomach lining contains the glands and gastric pits. The glands are located in the mucous membrane's lamina propria and open into the bases of the gastric pits formed by the epithelium. Mucus, pepsinogen, hydrochloric acid, intrinsic factor, gastrin, and bicarbonate are all secreted by the glands' various cells.
Gastric glands are mostly exocrine glands that are found within the gastric mucosa–the mucous membrane of the stomach–below the gastric pits. The mucosa of the stomach is pitted with numerous gastric pits, each containing 3-5 gastric glands. Foveolar (mucus), chief cells, and parietal cells are exocrine gland cells. The pyloric gland, which is an endocrine gland that secretes the hormone gastrin produced by its G cells, is the other type of gastric gland.

Thus, The gastric glands contain three types of cells. Mucous cells secrete an alkaline mucus that protects the epithelium from acid attack (HCl). Hydrochloric acid is secreted by the parietal cells, while pepsin, a proteolytic enzyme, is secreted by the chief cells.

Note:
The cardiac glands are found in the stomach's cardio, which is the part closest to the heart and encloses the opening where the esophagus meets the stomach. Only cardiac glands are found here, and their primary function is mucus secretion. They are smaller and more shallowly positioned in the mucosa than the other gastric glands. Simple tubular with short ducts or compound racemose resembling the duodenal Brunner's glands are the two types.
