BIO302: Human Anatomy

Unit 2: Integumentary System   The integumentary system (which is primarily comprised of the skin) covers the organ systems of the body, providing structure, insulation, and a first line of defense against infection.  In this unit, we will study the integumentary system by taking a close look at the structure of skin, hair, nails, and cutaneous glands.  Upon completion of this unit, you should understand why the skin lays on the body as it does and be able to explain the functional importance of the integumentary system.
