Question

What r the Materials used for demonstrating that how stomach is protected from acids

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.
