Cilia, tiny muscular, hair-like projections on the cells that line the airway, are one of the respiratory system’s defense mechanisms. Cilia propel a liquid layer of mucus that covers the airways.
What forms a protective case around your lungs?
The top and sides of the thorax are formed by the ribs and attached muscles, and the bottom is formed by a large muscle called the diaphragm (DYE-uh-fram). The chest walls form a protective cage around the lungs and other contents of the chest cavity.
What are the mechanisms of lungs?
When you breathe in, or inhale, your diaphragm contracts and moves downward. This increases the space in your chest cavity, and your lungs expand into it. The muscles between your ribs also help enlarge the chest cavity. They contract to pull your rib cage both upward and outward when you inhale.
How do the lungs protect themselves?
Mucus (a thick liquid) is produced in the walls of the small airways to help keep your lungs clean and well lubricated. It is moved by tiny hairs called cilia that line your airways. They move back and forth sweeping a thin layer of mucus out of your lungs and into your throat. Unwanted materials stick to the mucus.

What is the main function of mucus?
