Tracheal ciliated cell
Make it clearer
A tracheal ciliated cell is part of the inner lining of the trachea. Its surface carries cilia, slender hairlike projections that extend into the space where air passes.
Those cilia do not move independently. Their coordinated beating works like a conveyor belt, carrying mucus and the particles trapped in it away from the lungs.
In brief
A tracheal ciliated cell is an epithelial cell that reaches the surface of the mucosa and bears slender cilia on its apical surface.
The coordinated beating of its cilia propels mucus and trapped particles away from the lungs.
