Mucus in the mammalian respiratory system captures inhaled dirt and microorganisms. The mucus layer traps these foreign particles, preventing them from reaching the lungs and potentially causing infection or damage. The mucus is then either expelled through coughing or sneezing or moved by the cilia towards the throat to be swallowed or expectorated.
