Nasal epithelium. Coloured scanning electron micrograph (SEM) of the lining of the nasal cavity. The nasal cavity contains both ciliated and non-ciliated (secretory) cells. The cilia (hair-like,pink) help to move mucus (produced by secretory cells) and foreign bodies away from the respiratory tract and towards the pharynx in the throat,where it can be swallowed.
