5. Integumentary System  The integumentary system is composed of the skin, nails, and glands  The skin forms a protective covering for the body that, when unbroken, prevents entry of bacteria and other invading organisms. The skin also protects the body from water loss and the damaging effects of ultraviolet light. Other functions include regulation of body temperature and synthesis of vitamin D.
