The functions of the skin are diverse and go beyond simple defense. It controls body temperature via sweating and vasodilation, acts as the body's first line of defense against infections, and sends sensory data via a complex network of nerve endings. In addition, the skin contributes to the creation of vitamin D, which is necessary for strong bones. All of its layers—the dermis, the epidermis, and the subcutaneous tissue—have distinct roles in maintaining the body's ability to communicate with and defend the outside world.<end_of_turn><eos>
