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.

For a long time, almost all attention was on the motile cilia because their function was readily observable. But scientists, starting with Alexander Kowalevsky had reported the presence of single ...

They observed that the cilia contained motor proteins that are responsible for active motion in so-called motile cilia, the kind known to wiggle that are only observed in the lungs, the middle ear, ...

The airways, the network of tubes that pipes air into the lungs, deploy several defenses against bacteria. The liquid that coats the lining of the airways teems with microbe-fighting molecules and ...

Your body has natural defenses that protect against lung and respiratory health threats. Mucus, specialized immune cells, and ...

Cilia are outgrowths of the plasma membrane of eukaryotic cells that contain a specialised cytoskeleton. Motile cilia are present on multiciliated cells and use this cytoskeleton to move fluid ...

It develops when hair-like fibers called cilia disappear from the bronchial tubes, making it difficult to cough mucus from the lungs. There isn’t a cure for chronic bronchitis. To receive a ...
