What is it called that acts like a tiny broom that sweeps of the dirt in our nose?

The tiny structures that act like a broom to sweep dirt and mucus out of our nose are called cilia. These microscopic hair-like projections line the respiratory tract and move in a coordinated manner to push trapped particles and pathogens toward the throat, where they can be swallowed or expelled. This action helps keep the airways clear and protects the respiratory system from infection.
