You will find out how to keep these body parts healthy!
  • First you need to know the structure of your hair, skin, and nails and how each part works!!!
1. Integumentary System
    • Covers and protects body
    • Made up of skin, hair, and nails
2. Skin
    • Largest organ in body
    • Has nerve cells that help detect pain, pressure, heat cold, and touch
    • Protective layer from germs
Maintain a healthful body temp.
  • Removes waste from body
3. Two Layers of Skin
    • Epidermis – outer layer which is constantly shed and replaced
    • Dermis – layer below epidermis that contains hair follicles, glands, blood vessels and nerves
4. Melanin
    • Protects you from ultraviolent radiation
    • Pigment that gives skin its color
    • More Melanin=Darker skin tone
5. Glands
    • Sweat glands – rids the body of salt and helps cool the body by releasing sweat through pores
6. Nails
    • Composed of dead cells and keratin, a tough protein
7. Hair
    • Dead cells filled with keratin
    • Protects skin and helps maintain body temp
      • Goosebumps
      • Prevents loss of heat through head
    • Each hair grows in a hair follicle
8. Hair follicle– a depression on the surface of the skin that contains nutrients needed for hair to grow
A. Sunburn –
    • Caused by UV rays from the sun
    • People with fewer amounts of melanin are more likely to be sunburned
    • Can be prevented by wearing sunblock (at least SPF 30!!!)
B. Skin Cancer
    • Also called melanoma
    • Can be obtained from the sun
    • Studies have shown tanning booths may
    • cause skin
    • cancer
A – Asymmetry
    • If your mole is NOT the same on both sides, it could be cancerous
B – Border Irregularity
    • If the outside borders are shaped oddly, the mole may be cancerous.
C – Color
    • If your mole is black with a blueish tint, it may be cancerous
D – Diameter
    • Check for moles that are wider than ¼ of an inch, or larger than the size of a pea.
C. Acne
    • Lesions on the skin filled with excess oil and dirt which encloses the skin’s pores.
    • To prevent pimples:
      • Wash face daily with facial cleanser that contains Benzoyl.
      • Moisturize
      • Keep hands off your face
D. Athlete’s Foot
    • Fungal infection of the skin between the toes
    • Caused by sweating and heat
    • Highly contagious
    • Wear sandals or other foot coverings when in locker room or shower!
E. Ringworm
    • Common fungal infection of skin
    • Ring-shaped
    • Scaly, blistery patches form
