1. Skin

   • Epidermis
     • Stratified squamous
     • Stratum basale
     • Stratum spinosum
     • Stratum granulosum
     • Stratum lucidum
     • Stratum corneum
     • No blood vessels
   • Dermis
     • Papillary layer
     • Reticular layer
     • Hair roots and glands
   • Hypodermis
     • Subcutaneous tissue
     • Thickness varies depending on the region

2. Burns

   • First-degree (superficial) burns
   • Second-degree (partial thickness) burns
   • Third-degree (full thickness) burns

3. Inflammation

   • nflammation is a nonspecific response to injury or infection. Caused by physical trauma, heat, chemical or infection
   • 5 cardinal signs
     • Redness
     • Swelling
     • Heat
     • Pain
     • Loss of function
   • 3 types
     • Serous inflammation
     • Fibrinous inflammation
     • Suppurative inflammation

4. Lymphatic drainage

   • key role in the immune system
   • Maintain fluid balance
   • Aids in absorption of fats and fat-soluble nutrients
   • Obstruction of the drainage
     • Swelling of tissue

5. Infection

   • entry and multiplication of microorganisms in host; not necessarily synonymous with disease
   • Caused by
     • Viruses
     • Bacteria
     • Fungi
     • Parasites
   • Mode of transmission
     • Direct contact like shaking hands
     • Indirect like insect bites

6. Normal commensal flora

   • ecological communities of commensal, symbiotic and pathogenic microorganisms found in/on multicellular organisms
   • made up mostly of bacteria
   • 3 developmental changes
     • Weaning
     • Eruption of teeth
     • Cessation of ovarian function

7. Microorganisms

   • Pathogenecity
     • It is the ability of the pathogen to cause disease
   • Bacterial resistance
     • It happens when the bacteria are treated with antibiotic, most of them dye but small group may survive

8. Burn healing

   • Healing/repair is the body’s attempt at restoring the structure and function of injured tissue
   • 4 stages
     • HEMOSTASIS
     • INFLAMMATION
     • PROLIFERATION
     • REMODELING
   • Affecting factors
     • Age
     • Diet
     • Type of wound
