Please note the following in respect to your queries: The mucus secreted by different parts of our bodies have special functions. In our nose, it serves as a lubricator and stops dirt and dust from going deep into the nose and also aids breathing. In our stomach, it forms a layer between the deadly gastric juices and the lining of the stomach walls. This mucus lining prevents the acid present in the gastric juices from damaging the stomach. This wall created by the mucus layer is called the mucus membrane. It behaves like an acid-proof glove that the stomach uses to save itself from getting burnt while using harmful acids.
