The integumentary system is the body’s largest organ, forming a physical barrier between the exterior and interior environments it protects and maintains. The epidermis, dermis, hypodermis, associated glands, hair, and nails comprise the integumentary system. Apart from its barrier function, this system is involved in a variety of complex procedures such as body temperature regulation, cell fluid management, vitamin D synthesis, and stimulus detection.
