After you have mastered the material in this chapter, you will be able to: Explain the importance of understanding both anatomy and physiology when studying the body; illustrate body organization from simple to more complex levels; describe the locations and characteristics of the four main tissue types; describe the body organ systems, their general functions, and the major organs contained in each;. | 23 The Integumentary System Learning Outcomes (cont.) Describe the functions of skin. Describe the layers of skin and the characteristics of each layer. Explain the factors that affect skin color. Summarize types of common skin lesions. Learning Outcomes (cont.) Describe the accessory organs of skin along with their structures and functions. Explain the process of skin healing, including scar production. Describe the common diseases and disorders of the skin. Introduction Integumentary system Skin Body’s outer covering Largest organ Accessory organs: Hair follicles Nails Skin glands Learning Outcome: Describe the functions of skin. Your skin accounts for approximately 15% of body weight.

Protection First line of defense against bacteria and viruses. Protects underlying structures from ultraviolet (UV) radiation and dehydration. Functions of the Integumentary System (cont.) Body temperature regulation If too hot Dermal blood vessels dilate More blood to surface so heat escapes If too cold Dermal blood vessels constrict Prevents heat from escaping Learning Outcome: Describe the functions of skin. When a person is hot, dermal blood vessels dilate, which is why a person’s skin becomes pinkish. Because the dermal blood vessels are dilated, more blood than normal passes through the skin. This is beneficial because blood carries a lot of the body’s heat. When the blood gets close to the body’s surface (to skin), the heat can escape. On the other hand, if a person is cold, the dermal blood vessels constrict, preventing the heat in blood from escaping. Functions of the Integumentary System (cont.)
