The stomach- histology
Key:
- G- mucosa containing glandular tissue; different areas of the stomach contain different types of cells which secrete compounds to aid digestion. The main types involved are:
parietal cells which secrete hydrochloric acid
chief cells which secrete pepsin
enteroendocrine cells which secrete regulatory hormones.
- MM- muscularis mucosae
- SM- submucosa
The stomach contains three layers of involuntary smooth muscle which aid digestion by physically breaking up the food particles;
- OM- inner oblique muscle
- CM- circular muscle
- LM- outer longditudional muscle
