Cilia are hair-like structures found on the surface of various types of cells in many organisms, including humans. They play essential roles in movement, sensory functions, and the transport of substances; for example, cilia are found in the respiratory tract, where they help move mucus and trapped particles out of the lungs. In unicellular organisms, like certain protozoa, cilia can aid in locomotion. Additionally, cilia are involved in signaling pathways and can be found in the kidneys and other organs.
