The Integumentary System

The integumentary system (From Latin integumentum, from integere 'to cover'; from in- + tegere 'to cover'[1]) is the organ system that protects the body from damage, comprising the skin and its appendages[2][3] (including hair, scales, feathers, and nails). The integumentary system has a variety of functions; it may serve to waterproof, cushion, and protect the deeper tissues, excrete wastes, and regulate temperature, and is the attachment site for sensory receptors to detect pain, sensation, pressure, and temperature. In humans the integumentary system also provides vitamin D synthesis.
