The epithelium found in hollow organs (like bronchioles) are originally _____ epithelium bearing fine brush-like structures on its free surface.

Columnar epithelium is found in the lining of hollow organs like bronchioles.

The columnar epithelium is composed of a single layer of tall and slender cells. Their nuclei are located at the base. If the
columnar bear cilia on their free surface they are called ciliated epithelium. Their function is to move particles or mucus in a specific direction over the epithelium. They are mainly present in the inner surface of hollow organs like bronchioles and fallopian tubes.
