What is the purpose of mucus in the airway?
The airway surface liquid (ASL), often referred to as mucus, is a thin layer of fluid covering the luminal surface of the airway. The major function of mucus is to protect the lung through mucociliary clearance against foreign particles and chemicals entering the lung.
What is the importance of cilia and mucus in the respiratory system?
The bronchus in the lungs are lined with hair-like projections called cilia that move microbes and debris up and out of the airways. Scattered throughout the cilia are goblet cells that secrete mucus which helps protect the lining of the bronchus and trap microorganisms.
What and mucous work to trap dirt and germs before we inhale?
Goblet cells produce mucus which traps dust, dirt and bacteria to prevent them entering the lungs. Cilia are small hairs which beat to push the mucus back up the trachea so it can be swallowed and destroyed in the stomach. Clean air then enters the two bronchi, one bronchus going to each lung.
What physically moves the mucus with particles trapped in it up and out of your lungs?
The cilia are specialized organelles that beat in metachronal waves to propel pathogens and inhaled particles trapped in the mucous layer out of the airways.
How can I clean my respiratory system?
Ways to clear the lungs
- Steam therapy. Steam therapy, or steam inhalation, involves inhaling water vapor to open the airways and help the lungs drain mucus.

Your trachea is divided into 2 air passages called bronchial tubes. One bronchial tube leads to the left lung, the other to the right lung
What is the pathway of air into the lungs?
