Structure and Function
5 INTEGUMENTARY SYSTEM Structure and Function Epidermis Dermis Subcutaneous tissue Accessory organs Glands Sebaceous (oil) Sudoriferous (sweat) Hair Nails Pedagogical Note: For instructors who prefer extensive anatomy and physiology coverage, refer to the Respiratory System presentation for an example of such coverage. You may expand the anatomy and physiology sections by using the Respiratory System chapter as a guide to lengthen anatomy and physiology sections in other chapters. In addition, you may encourage students to complete TermPlus, the powerful interactive multimedia program where they can concentrate on reinforcing anatomy and physiology. 2
