Columnar epithelium: The columnar epithelium have cells which are similar to pillar to column. The nuclei of these cells are located at the bottom and are present in the lining of the stomach and intestine The main function of columnar epithelium are absorption and secretion.
Ciliated epithelium: The ciliated epithelium are the columnar epithelium that have cilia. They are present in the inner surface of bronchioles and fallopian tubes. The main function these cells is to move particles in apecific direction.
Therefore, it can be concluded that the presence of cilia helps in differentiating between columnar epithelium and ciliated epithelium.
