Biological barriers include the Langerhans cells of the epidermis, the macrophages of the dermis, and the DNA itself. The skin plays an important role in body temperature regulation by using the sweat glands of the skin to cool the body, and constriction of dermal capillaries to prevent heat loss.ells of the Epidermis.
