This article will cover the anatomy and function of the ... and hair-like projections called cilia that line the inside of the trachea and help move foreign particles up and out of the airway.

The trachea is also lined with tiny hair-like structures called cilia. These help push mucus that contains debris or pathogens out of the trachea. A person then either swallows or spits out the mucus.

They’re called anthrobots. A team of scientists created them using human cells from the trachea. Part of the reason why they used those cells is because they are covered with cilia, or tiny, hair-like ...
