Attached is a photo taken from the lens of a microscope examining an epithelial tissue. What is shown is an example of a Pseudostratified Ciliated Epithelium, most probably coming from the respiratory tract. Pseudostratified tissues are commonly found in the respiratory tract. The cilia function as mechanical appendages, most active during expulsion of sputum. Looking closely, oval shaped translucent cells can be located near the apical surface. These structures are named Goblet Cells, and its main function is to produce mucus that serves as protection for the respiratory tract.

The distinct arrangement of cells that appear layered but are actually all connected to the basement membrane is evident in this image of pseudostratified ciliated epithelium. Because it emphasizes the tissue's function in removing mucus and trapped particles from the respiratory tract, the presence of cilia on the apical surface is particularly intriguing. It's amazing how this unique structure helps to preserve respiratory health and protect the lungs.
