Cilia.
Cilia are short, thin, hair-like projections that extend from the surface of a cell. They wave in a coordinated back-and-forth motion to move fluid or particles along the cell's surface. Cilia are found in various types of cells, including those lining the respiratory tract to help move mucus and particles out of the lungs.
