The tiny projections are called cilia.
Infectious agents, small aerosol and dust particles are trapped in the mucus elevator to prevent their invasion in lungs.

Cilia are the microscopic hairlike projections found in the cells lining most of the respiratory tract. They help to sweep mucus and trapped particles out of the airways to protect the lungs from infections and irritants.
The bronchi are located in the lungs and are coated with mucus. They also have cilia which are small hair-like projections on the surface of the bronchi that move the mucus towards the outside of the body.
Cilia are hairlike structures located in the respiratory system. They help to sweep mucus and foreign particles out of the airways, assisting in the protection of the lungs from potential irritants or infections.
The cilia on their surface trap dust and microbes, then pass the trapped substances along with mucus to the throat, where they can then be swallowed. This then protects the lungs.
the function of the mucus blanket in the lungs is to filter and moisten the air.
mucus- mucus in the lungs makes breathing difficult
Your lungs are the reasons you body has Oxygen. In your lungs, we do produce mucus, which we cough up because of the cilia in our lungs. Smoking causes this cilia to not move the mucus out of your lungs which in turn causes problems.
Mucus
Cilia are not typically found in the heart. They are more commonly found in the respiratory tract, where they help move mucus and trapped particles out of the lungs.
