Mucus Role in Stomach

1. Protection of the Stomach Lining: The stomach contains strong digestive acids, such as hydrochloric acid, which are necessary for breaking down food. However, these acids can also be harmful to the stomach lining. Mucus forms a protective layer on the inner surface of the stomach's mucous membrane, creating a barrier between the acidic contents and the stomach wall. This prevents the stomach from digesting itself and protects it from erosion and damage due to the corrosive nature of gastric juices.
2. Lubrication: Mucus acts as a lubricant, allowing food to move smoothly through the stomach and aiding in the process of digestion. This lubrication helps prevent food from sticking to the stomach walls and facilitates the mixing of food with digestive enzymes.
