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.

In recent years, 3D printing has achieved aesthetically awesome and profoundly practical feats, the latest of which is a perfect marriage of both: 3D-printed hair. And while that description might ...

The air that enters the nasal cavity flows down the trachea ... cells produce mucus which traps dust, dirt and bacteria to prevent them entering the lungs. Cilia are small hairs which beat ...

The cells of the inner trachea are covered in hair-like projections called cilia, which move together to help push out mucus. In their new study, the Levin lab grew similar organoids under ...

Air from outside the body comes in through a pathway called the trachea. It then goes ... These are called cilia. They clean up any dust or dirt that’s found in the air you breathe.

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 ...
