Final answer:
Cilia have a movement function in the body.
Step-by-step explanation:
The function of cilia is movement. Cilia are hair-like structures found on the surface of many cells in the body. They beat in coordinated waves, creating a fluid movement that helps the cell or organism move. For example, cilia in the respiratory tract help move mucus and debris out of the lungs, while cilia in the reproductive system help move eggs along the fallopian tubes.
