Examples: epithelium of trachea, epithelium of uterine tube.[FMA]. Ciliated columnar epithelium in the pulmonary system is interspersed with goblet cells that secrete mucous to form a mucosal layer apical to the epithelial layer. The rowing-like action of epithelial cilia work in tandem with goblet cells to propel mucus away from the lungs, preventing particulate matter from causing infection[http://www.bio.davidson.edu/people/kabernd/berndcv/lab/epithelialinfoweb/ciliated%20columnar%20epithelium.html] UBERON:0007592 In humans, Ciliated columnar epithelial cells are found mainly in the tracheal and bronchial regions of the pulmonary system and also in the fallopian tubes of the female reproductive system ciliated epithelium
