Tissues to Tattoos 1. Why do some areas of the body have simple squamous epithelium and other areas have stratified squamous epithelium?
Stratified squamous epithelium is used in areas of the body that undergo more abrasion (Epithelial Cells) than then areas of the body that require just having simple squamous epithelium (Epithelial Cells). Examples of areas that need stratifies squamous epithelium are the outmost layer of skin as well as the lining of the mouth and esophagus. In contrast, areas that use simple squamous epithelium include capillaries, alveoli, and various tissue that require rapid diffusion.
2. List and explain the different characteristics of each membrane (physical barrier) in our bodies. Select one of the membrane types and explain what would occur if it was damaged.

First degree burns are the least severe and only involves the epidermis. First degree burns are usually caused by the sun and result in slight swelling, pain, and redness. Second degree burns involve the epidermis as well as the dermis. These burns involve blistering in addition to the swelling, redness and pain. Second degree burns may appear white, red, or even tan and can produce scarring. The last type of burn is a third degree burn. These are the most severe, though many often there is no pain because the nerve endings are damaged. Third degree burns effect the epidermis, the dermis and extends down into the subcutaneous layer and can appear white or black and leathery. Unlike the other 2 types, third degree burns often require skin grafts to fully heal. (Wikipedia, 2014) Though the three types vary in severity from each other, all three damage the
