MICROANATOMY

Detailed explanation-1: -Cilia: Cilia are tiny, hair-like, motile (they can move) structures on the surface of the cell that help move entire cells or can move substances along the outer surface of the cell. Ciliated cells usually have hundreds of cilia on their surfaces.

Detailed explanation-2: -The cilia beat in a coordinated fashion across the epithelium in order to move bacteria, virus, epithelial debris, and other unhealthy items up and out of the airway. The goblet cells of the epithelium produce mucous which assist collecting the debris for expulsion out of the airway.

Detailed explanation-3: -Ciliated columnar epithelium is composed of simple columnar epithelial cells with cilia on their apical surfaces. These epithelial cells are found in the lining of the fallopian tubes and parts of the respiratory system, where the beating of the cilia helps remove particulate matter.
