Answer 1

The main job of mucous is to provide a barrier between underlying tissue and debris, viruses, bacteria, etc. It also flows through areas using tiny hairs to push it along, where the offending debris can be dealt with later.

Many pathogens rely on direct contact with tissue and have even developed their own anti mucous adaptations to get around it.
