WebApr 13, 2024 · A Sensible System Keeps the Lungs Clean. The tissue of the respiratory tract consists of a complex system of cells with several fixed functions. The system is collectively called the mucociliary epithelium. Mucus means slime and is the Latin name for the mucus that covers and protects the mucous membrane. The respiratory epithelium lining the upper respiratory airways is classified as ciliated pseudostratified columnar epithelium. This designation is due to the arrangement of the multiple cell types composing the respiratory epithelium. While all cells make contact with the basement membrane and are, therefore, a single layer of cells, their nuclei are not aligned in the same plane. Hence, it appears as though several layers of cells are present and the epithelium is called pseu…
