Code

A simple columnar epithelium is a columnar epithelium that is uni-layered. In humans, a simple columnar epithelium lines most organs of the digestive tract including the stomach, small intestine, and large intestine. Simple ciliated columnar epithelia line the uterus. Simple columnar epithelia are further divided into two categories: non-ciliated and ciliated.

Ciliated

Ciliated columnar epithelia move mucus and other substances via cilia, and are found in the upper respiratory tract, the Fallopian tubes, the uterus, and the central part of the spinal cord.

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