Ciliated Epithelium: Its Functions And Significance

WebNov 13, 2024 · This epithelium is composed of ciliated cells, which have tiny hair-like projections that help to move mucus and other particles out of the respiratory tract. Pseudostratified ciliated columnar epithelium is important for keeping the respiratory tract clear of debris and for protecting the lungs from infection. 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.
