Cilia are elongated motile cylindrical projections from the apical cell membrane, approximately … WebThese ciliated conducting airway epithelial cells are very sensitive to direct-acting toxicants (Cao et al., 2024) while the secretory cells (i.e., mucous and Clara cells) appear to be less sensitive. Cilia may be reduced in length or diameter and exhibit reduced density, and the ciliated cells may exhibit a variety of cytoplasmic changes ...
WebMar 3, 2024 · These non-ciliated cuboidal cells contribute to the production of surfactant (reduces tension in the narrow lumen of the respiratory portion of the airway), detoxifies air and may differentiate into bronchial epithelial cells to replace older cells.

WebAnswer: Ciliated cells remove mucus from the airways, and together with mucus, everything that got stuck to it. The cilia beat upwards, creating so called escalator, and this action removes dust, debris, dead cells that got into the lungs and expired, and so on. Mucus secreting cells extend to t...
