Final answer:
The secretory cell types in the stomach and their products include parietal cells, chief cells, mucous neck cells, and enteroendocrine cells. Parietal cells secrete hydrochloric acid, chief cells secrete pepsinogen, mucous neck cells secrete mucus, and enteroendocrine cells secrete hormones.
Step-by-step explanation:
The secretory cell types in the stomach and their products include:
- Parietal cells: These secrete hydrochloric acid which helps activate the protein-digesting enzyme, pepsin.
- Chief cells: These secrete the enzyme pepsinogen, which is converted into pepsin in the presence of hydrochloric acid.
- Mucous neck cells: These secrete mucus, which helps protect the stomach lining from acid and abrasion.
- Enteroendocrine cells: These secrete hormones such as gastrin, which regulates gastric acid secretion and motility.
