The lungs are protected by several mechanisms, including the mucociliary escalator, which traps and expels harmful particles and pathogens through mucus and cilia. Additionally, immune cells within the lung tissue help identify and eliminate foreign invaders. The respiratory epithelium also provides a barrier against environmental pollutants. Furthermore, avoiding smoking and maintaining good air quality are crucial for lung health.
