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 ...

Mechanical engineers have developed a system of artificial cilia capable of monitoring mucus ... with an airway stent within an artificial trachea and sheep trachea. Sensing signals are ...

Cilia are small hairs which beat to push the mucus back up the trachea so it can be swallowed and destroyed in the stomach. Clean air then enters the two bronchi, one bronchus going to each lung.

But if you breathe in harmful things like cigarette smoke, the cilia can stop working. This can lead to health problems like bronchitis. Cells in your trachea and bronchial tubes make mucus that ...

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 ...

In the former he found that the bronchial epithelium contained more goblet cells, shorter cilia and a thicker epithelium ... 22 From the trachea and bronchi of human beings (or animals) a cup ...
