Visceral Pleura
The visceral pleura is made up of a simple squmous/cuboidal epithelium (the mesothelium) and some connective tissues beneath it. Small

Wall of Bronchiole at Higher Magnification
If you look at the epithelium carefully, you will see that there are three main types of cells present. The
