1.	What is the advantage of ciliated mucous membrane in nasal passage?
Answer» Cells in the mucous membrane produce mucus and have tiny hairlike projections (cilia). Usually, the mucus traps incoming dirt particles, which are then moved by the cilia toward the front of the nose or down the throat to be removed from the airway. This action helps clean the air before it goes to the lungs.
