Infectious agents, small aerosol and dust particles are trapped in the mucus elevator to prevent their invasion in lungs.
cilia
Dust particles are trapped in mucus in the respiratory tract, such as the nose and throat, and in hair on our skin. Mucus acts as a sticky barrier that captures dust particles as we breathe, while hair on our skin can also trap dust before it reaches our respiratory system.
Mucus and dust are trapped and swallowed at the back of your throat by a cilia cell.
Emphysema
Mucus and dust are two things that are trapped and swallowed at the back of the throat by cilia cells.

Microorganisms trapped in the mucus of the nasal cavity are usually moved by the cilia towards the back of the throat and swallowed. From there, they enter the digestive system where they are exposed to stomach acid that can help kill them.
When the lining of the sinuses is at all swollen, the swelling interferes with the normal flow of mucus. Trapped mucus can then fill the sinuses, causing an uncomfortable sensation
The tiny projections are called cilia.
The function of cilia is to remove foreign particles and mucus from the surface of the respiratory system. This is to prevent the blockage of airways.
nose: airways are lined with cells that can produce mucus in which dust and microbes get trapped.
