2. Protects the body's internal living tissues and organs Protects against invasion by infectious organisms Protects the body from dehydration Protects the body against abrupt changes in temperature Helps dispose of waste materials Acts as a receptor for touch, pressure, pain, heat and cold Stores water, fat, and vitamin D. Functions
3. outermost layer epithelium strata or layers keratin (a fibrous protein) no blood vessels or nerve supply in epidermis Epidermis
4. Sebaceous glands Arrector pili Shaft of hair Hair follicle Blood vessels Lymph vessels Sensory receptors Nerve fibers Muscle fibers Dermis of Corium
5. Connective tissue layer Specializes in formation of fat Adipose or fat cells provide a food reserve and insulation Subcutaneous Layer
7. First-degree burns are considered mild compared to other burns. They result in pain and reddening of the epidermis (outer layer of the skin). Second-degree burns affect the epidermis and the dermis (lower layer of skin). They cause pain, redness, swelling, and blistering. Third-degree burns go through the dermis and affect deeper tissues. They result in white or blackened, charred skin that may be numb.
8. First-degree burns may be treated with skin care products like aloe vera cream or an antibiotic ointment and pain medication such as acetaminophen. Second-degree burns may be treated with an antibiotic cream or other creams or ointments prescribed by a doctor. The treatment of third-degree burns may require the process of skin grafting or the use of synthetic skin. Severe burns covering large parts of the body may need more intensive treatments such as I.V. antibiotics to prevent infection or I.V. fluids to replace fluids lost when skin was burned.
