  3. The largest organ of the body Changes in the skin often indicate the presence of other body system disorders including anemia, respiratory disorders, liver disorders, cancer, and shock Integumentary Facts

  4. Epidermis • Outermost layer of the skin • Composed of a surface of dead cells with an underlying layer of living cells • Contains sebaceous glands as well as hair follicles • Melanocytes (produce melanin) are located in the epidermi Layers of Skin
