Where are epithelial cells?
Take a quick look at the skin on your hands. Even if you think your skin is one smooth surface, it is actually made of millions of epithelial cells that are tightly packed next to each other.

They are a barrier between the inside and outside of your body and are often the first place that is attacked by viruses as they begin their invasion deeper into the body.
