Final answer:
Intermediate gastric glands are composed of parietal cells, chief cells, mucous neck cells, and enteroendocrine cells. Parietal cells produce hydrochloric acid and intrinsic factor, chief cells secrete pepsinogen, mucous neck cells secrete mucus, and enteroendocrine cells secrete hormones such as gastrin.
Step-by-step explanation:
The intermediate gastric glands are composed of several types of cells. Parietal cells are located in the middle region of the gastric glands and produce hydrochloric acid (HCl) and intrinsic factor. HCl is responsible for the high acidity of the stomach contents, which helps in digestion and killing bacteria. Intrinsic factor is necessary for the absorption of vitamin B12.
Chief cells are another type of cell in the gastric glands that secrete pepsinogen, the inactive form of the enzyme pepsin, which is responsible for protein digestion. Mucous neck cells secrete mucus, which protects the stomach lining from the acidic environment and helps lubricate and protect the stomach walls.
Enteroendocrine cells are also found in the gastric glands and secrete various hormones, including gastrin. Gastrin plays a role in stimulating the release of gastric juices and promoting gastric motility.
