The human tracheobronchial tree is lined by pseudostratified, ciliated epithelium from the larynx down to the level of the terminal bronchiole. The nasal cavity (apart from its most anterior portion) and the paranasal sinuses are also lined by ciliated epithelium.
The epithelium of the human fallopian tube is a mixture of ciliated and nonciliated cells. Scattered ciliated cells are also found in the endometrium. The function of these ciliated cells is generally believed to be the transport of eggs, zygotes, and secretions. The cilia may further help to maintain the patency of the oviductal lumen
