Pseudostratified ciliated columnar epithelial tissue, illustration. Epithelial tissues line cavities and surfaces within and on the body. The pseudostratified ciliated columnar type makes up the lining of parts of the respiratory tract. It contains gland cells and cilia (red, top), that secrete and transport mucus to protect the lungs. Cell nuclei (round) are red. For a set of images showing epithelial tissue types, see C023/8593 to C023/8597.
