Ciliated columnar epithelial cells are a type of tissue found in various parts of the body, particularly in the respiratory tract and the fallopian tubes. These cells are tall and column-like, and they have tiny hair-like structures called cilia on their surface. The cilia help to move mucus and trapped particles out of the airways, keeping the lungs clear of debris and pathogens. In addition to their role in the respiratory system, ciliated columnar epithelial cells also play a crucial part in the reproductive system. In the fallopian tubes, for example, the cilia help to transport the egg from the ovary to the uterus. This movement is essential for reproduction and overall reproductive health.
