In humans, a simple columnar epithelium forms a lining in the [[uterus]] and in most organs of the [[digestive tract]] including the [[stomach]], [[small intestine]], and [[large intestine]]. Simple columnar epithelia are further divided into two categories: nonciliated and ciliated. ==Nonciliated== ''Nonciliated columnar epithelia'' do not have [[cilia]], and are found in the [[gastrointestinal tract]] and the [[gallbladder]] where they perform [[secretion]] and [[absorption]]. ==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]]. Ciliated columnar epithelium lines the [[lumen]] of the [[uterine tube]], where currents generated by the [[cilia]] propel the [[egg cell]], toward the [[uterus]]. ==Additional images== <gallery> Image:Illu epithelium.jpg|Types of epithelium.
