Ciliated columnar epithelium is a type of tissue made up of tall, column-like cells that have tiny hair-like structures called cilia on their surface. This epithelium is primarily found in the respiratory tract, where it helps to move mucus and trapped particles out of the airways, keeping them clear of debris and pathogens. In addition to the respiratory system, ciliated columnar epithelium can also be found in the fallopian tubes, where it aids in the movement of the egg from the ovaries to the uterus. The coordinated beating of the cilia is essential for proper function in these areas.
