Epithelial cells help to protect or enclose organs. Most produce mucus or other secretions. Certain types of epithelial cells have tiny hairs called cilia, which help remove foreign substances. Epithelial cells are arranged in single, or multiple layers, depending on the organ and location.
Cilia are tiny hair-like organelles that reside on the surface of cells. In the human body, many are found on cells where they sweep debris away from the lungs and nasal cavities. They also line the Eustachian tubes and sinuses, as well as the fallopian tubes in women.
