The many cilia present on the surface of the cells of respiratory epithelium, along with the mucus producing goblet cells, are the functional units for the Mucociliary escalator:
The many cilia present on the surface of the cells of respiratory epithelium, along with the mucus producing goblet cells, are the functional units for the Mucociliary escalator:
*Cilia on the respiratory epithelium beat in a co-ordinated manner
