Detailed explanation-1: -The pseudo stratified ciliated columnar epithelium lining the larynx produces mucus which traps debris in the air and the cilia moves the mucus and the debris into the pharynx where it is swallowed[1].

Detailed explanation-2: -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 pseudostratified (falsely layered).

Detailed explanation-3: -Found most heavily along the respiratory tract, pseudostratified ciliated columnar epithelial cells help trap and transport particles brought in through the nasal passages and lungs.
