The respiratory epithelium functions to moisten and protect the airways. It acts as a physical barrier to pathogens, as well as their removal in the mechanism of mucociliary clearance. The ciliated cells are the primary components in the mucociliary clearance mechanism. Each epithelial cell has around 200 cilia that beat constantly at a rate of between 10 and 20 times per second. The direction of their beat is targeted towards the pharynx, either upwards from the low… WebApr 11, 2024 · In our study, the rate of hamartomas containing PT component was similar to the literature (14.3%), and the epithelium of these structures consisted of ciliated or non-ciliated columnar cells.
