The functions of the integumentary system are far more important than most people think. Perhaps it is commonly known that this system, known as the skin, keeps the body together and protects the inner aspects of the body from harm, or cools the body. Those functions are overly simplified and only a fraction of the role this system plays in maintaining the balance, also known as homeostasis, of the body. It can be said that this system is the first line of defense or regulation. It provides these functions: resistance to trauma and infection, barrier functions, Vitamin D synthesis, sensation, and thermoregulation to fill its role (Saladin, Sullivan, & Gan, 2015, p. 177- 178).
