Question

Answer the following questions. The release of which juice from the inner wall of the stomach protects it against the HCI. With​

Answer 1

Answer:

In the stomach several mucosal defence mechanisms protect the stomach against hydrochloric acid and noxious agents. The pre-epithelial protection is made up by the mucus-bicarbonate barrier. Mucus and bicarbonate, secreted by mucus cells, create a pH gradient maintaining the epithelial cell surface at near neutral pH.

Answer 2

The release of mucus from the inner wall of the stomach protects it against the HCI.

• The mucus is present in the gastric juice of the stomach.
• Stomach mucus shields the stomach lining from the harmful effects of gastric fluids. Gastric secretions like hydrochloric acid are highly acidic and without this mucus, the acid would harm the stomach lining and cells.
• The mucus inside the stomach is rich in bicarbonates. Bicarbonates being alkaline protect the stomach from the high acidity of HCl.
