In the Integumentary comprise of structure and functions of our skin. The structure of our skin consists of two layers epidermis and dermis. The normal function of the epidermis being the outer portion, which in itself is also divided into thin layers called the Strata, is for protection of the body. It is also composed entirely of epithelial cells and contains no blood vessels. (COHEN. 2013, p.112) The epidermis is constantly lost with wear and tear because of its lack of blood vessels, so it has to get nourished via capillaries in the underlying dermis which has stem cells that produce new epidermal cells. (COHEN. 2013, p.113) The layer that all this happens in is known as the Stratum Basale and in here the cells constantly divide themselves and reproduce new cells. The new cells are then pushed to the surface and as they go through this process; they
