- - - - Hair- protects from heat loss, hair on head protects from trauma, shields skin from sunlight. Made up of dead keratinized cells
        
        Nails-contains hard keratin
        
        Sweat glands- contains myoepithelial cells
        
        Sebaceous glands- secretes oil
        
        Medulla-core of large cells and air space
        
        Cortex- several layers of flattened cells
        
        Cuticle- outer layer
      - Epidermis- superficial region contains epithelial tissue and is avascular
        
        Dermis-under epidermis, mostly fibrous connective tissue and is vascular
        
        Hypodermis- mostly adipose tissue that absorbs shock and insulates
  - - - Chemical barrier-secretes chemicals such as sweat and sebum
        
        Physical barrier-Flat, dead, keratinized cells of stratum corneum, surrounded by glycolipids, block most water and water-soluble substances. Helps protect the body from dangerous substances entering
        
        Biological barrier-Epidermis containing phagocitic cells
        Dermis containing macrophages
      - Regulating body temperature-Produces sweat and helps to keep the body from over heating.
        
        Metabolic function - synthesizes vitamin D need for Ca absorption in the intestines
        
        Blood reservoir-holds up to 5% of the bodies total blood volume
        
        Excretion of waste-can secrete ammonia, urea,uric acid
        Too much can cause dehydration
        
        Cutaneous sensations- part of the nervous system let the body know when its hurt, responds to outside stimuli
  - - - First- degree burns- epidermal layer only. localized redness, swelling and pain
        
        Second-degree burn- epidermal and dermal damage. Blisters appear
        First and second degree burns are considered partial thickness burns
        
        Third-degree burns- Full thickness burns, skin color turns gray-white, cherry red, or blackened
        There is no edema and its not painful because nerve endings are destroyed
    - - It assigns a percentage that is either nine or multiples of nine to determine how much of the body has been burned.
        
        Head and neck 9%
        
        Anterior and posterior upper limbs 18%
        
        Anterior and posterior trunk 36%
        
        Anterior and posterior lower limbs 36%
        
        Genitals 1%

- - - - This would be considered first-degree burns
    - - They are painful and covered with painful blisters.
        
        This area is covered in second- degree burns
      - Chest and abdomen
        
        Pale gray-white in color, there is little swelling and pain in this area
        
        This area is covered in third-degree burns
        
        This area will probably need skin grafts
        
        Since the skin is burned off the doctors should worry about fluid loss and and infection. An IV should be started to control fluid loss and antibiotics should be started
