What is the procedure you followed to demonstrate the role of mucus in protecting the
stomach from its own acids? What did you observe?
Answers
Explanation:
The stomach is protected by the epithelial cells, which secrete and produce a bicarbonate rich solution that coats the mucosa. Stomach protects itself from autodigestion for the continuous supply of bicarbonate stomach protect itself from whole acidic environment also. Enzymes, which make up part of the digestive juices are also secreted by the stomach wall, from gland with no barrier of mucus.
Explanation:
Gastric Mucus
Gastric mucus is a gel-mucous barrier secreted by epithelial cells and glandular cells in the stomach wall. It acts as part of a barrier that protects the stomach wall from the acid and digestive enzymes within the stomach lumen. This barrier is also made up of a bicarbonate secretion and the epithelial cells themselves, which are tightly joined together. Together, these components prevent the stomach from effectively digesting itself.
Mucus is secreted by the stomach epithelial cells, but the mucus is mainly secreted from foveolar cells, found in the necks of the gastric pits. Mucus-secreting cells are the most abundant cell type in the stomach, giving indications of how important mucus is to the functioning stomach.
