The Vital Role of Mucus in Respiratory Health
Mucus protects and maintains respiratory health through:
- Trapping Particles: Dust, pollen, bacteria, viruses caught in sticky mucus.
- Mucociliary Clearance: Cilia sweep mucus upward to throat for expulsion.
- Moisturizing/Lubricating: Prevents tissue drying and irritation.
- Immune Response: Contains antibodies, antimicrobial peptides, enzymes; traps pathogens for immune cells.
- pH Balance & Protection: Slightly alkaline pH inhibits pathogens; mucins/glycoproteins shield epithelium.
Mucus is essential for infection defense, particle removal, immune function, and moisture/pH balance.
