  6. 6. Integumentary System <ul><li>Integumentary system is composed of the skin. </li></ul><ul><li>Provides protection from injury, prevents dehydration, controls body temperature and excrete some wastes through sweating. </li></ul>Pg. 230
  7. 7. Integumentary System <ul><li>Skin is composed of two main layers: </li></ul><ul><ul><li>Epidermis </li></ul></ul><ul><ul><li>Dermis </li></ul></ul>Pg. 230
