‘Mucosal’ introduces mucosa, the tissue that lines your Nose, mouth and lungs. It is the innermost layer and functions in digestion and secretion. It is formed of epithelium cells and thin connective tissue. In addition, the mucosa contains specific goblet cells that cover viscous mucus throughout the gastrointestinal tract.
