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.

Mucosal membranes are made up of epithelial cells, mucus-secreting goblet cells, and hair-like projections called cilia that line the inside of the trachea and help move foreign particles up and ...

Air pollution is the second leading risk factor for death globally, with most of the world population subject to harmful air ...

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 projections.

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 ...

They aren’t really hairs. They’re sensory cells. Hair cells have tiny, bristle-like tufts that stick out – called cilia – ...

The HEATR2 protein (red) is located in the body of airway cells lining the trachea, not in the cilia (green) or the nuclei (blue). Finding HEATR2 outside of the cilia was the first clue for Amjad ...

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 ...
