What is the mucous membrane?

The mucous membrane is a thin layer of tissue that lines various cavities and structures in the body, including the respiratory, digestive, and reproductive systems. It produces mucus, a sticky fluid that helps to protect and lubricate the tissues, as well as trap and remove foreign particles and pathogens.
