What is the significance of goblet cells on the respiratory epithelium?
What will be an ideal response?
The presence of goblet cells on the surface of the epithelium means that the epithelium will have a thin mucous layer resting on the epithelial surface. Such a mucous layer provides a "sticky" surface that bacteria, viruses, and other foreign particles can get trapped in, thus preventing their entrance into the lungs.
