Structure

Simple columnar epithelium is further divided into two categories: ciliated and non-ciliated.

Location

They are found in the respiratory tract. Due to the movement of the cilia, the mucous and air is pushed away to clear the respiratory tract.

Ciliated

Ciliated columnar epithelium moves mucus and other substances via cilia and is found in the upper respiratory tract, the Fallopian tubes, the uterus, and the central part of the spinal cord.They are the primary target of infection for "common cold viruses" such as coronaviruses, influenza virus and rhinoviruses. These viruses may kill the ciliated cells or stop the cilia beating. In either case, mucus builds up and forms a good site for secondary bacterial infections, resulting in mucus.

A ciliated columnar epithelium lines the lumen of the uterine tube, where currents generated by the cilia propel the egg cell toward the uterus.

Non-cilitated

This is found lining sections of the gastrointestinal tract and may be brush bordered.
