Schmidtea mediterranea Ciliated Cells (image) Stowers Institute for Medical Research Caption Centrioles (shown in green) serve as anchor points for cilia (shown in red) -- tiny projections on the surface of cells that help move fluid and mucus around the brain, lung, eye and kidney and propel eggs down fallopian tubes. The freshwater planarian Schmidtea mediterranea use ciliated cells lining its pharynx (shown above) to ingest food.
