It is a well known fact that the epithelial cells in the respiratory tract have hair like projections on the outer surface of the cells.
These kinds of hair like projections are otherwise known as cilia.
The cilia prevent the arrival of various waste materials.
It is the main reason why this cell gets this kind of name.
