Respiratory epithelium, or airway epithelium,[1] is a type of ciliated columnar epithelium found lining most of the respiratory tract as respiratory mucosa,[2] where it serves to moisten and protect the airways. It is not present in the vocal cords of the larynx, or the oropharynx and laryngopharynx, where instead the epithelium is stratified squamous.[3] It also functions as a barrier to potential pathogens and foreign particles, preventing infection and tissue injury by the secretion of mucus and the action of mucociliary clearance.
