2. Skin
• The skin is the largest organ of the body, with a total area of about
20 square feet. The skin protects us from microbes and the
elements, helps regulate body temperature, and permits the
sensations of touch, heat, and cold.
• Skin has three layers:
• The epidermis, the outermost layer of skin, provides a waterproof
barrier and creates our skin tone.
• The dermis, beneath the epidermis, contains tough connective
tissue, hair follicles, and sweat glands.
• The deeper subcutaneous tissue (hypodermis) is made of fat and
connective tissue.
• The skin’s color is created by special cells called melanocytes, which
produce the pigment melanin. Melanocytes are located in the
epidermis.

5. Skin Burns
• First-degree burns are red and painful. They
swell a little and turn white when you press on
them. The skin over the burn may peel off in a
day or two. These are the least severe type of
burn, affecting only the outer layer of skin.
• Causes: Sunburn and hot liquids

7. First degree burn
• Healing time: 3 to 6 days; the superficial skin
layer over the burn may peel off in 1 or 2
days.

8. Second Degree Burns
• A second degree (partial thickness) burn
damages the top layers of the skin &
• causes blistering. It can result in scarring and
may require a skin graft.

9. Second Degree Burns
• Second degree burns can result from:
• Hot liquids
• Flame Injury
• Scalding liquids

10. Second Degree Burns
• Signs and symptoms: Blisters, severe pain,
and redness. The blisters sometimes
• break open and the area is wet looking with a
bright pink to cherry red color.

13. Third Degree Burn
• A third degree (full thickness) burn destroys all
layers of the skin. Skin grafting is
• necessary to repair the skin
• Third degree burns can result from:
• Prolonged flame (house fire)
• Steam or scalding liquids
• Chemical or electrical injury

14. Third Degree Burn
• Signs and symptoms:

leathery, brown, or charred.
• There may be little or no pain or the area may
feel numb at first because of nerve damage.

16. Fourth Degree Burns
• A fourth degree (full thickness) burn destroys
all layers of the skin and involves tendons and
muscles. As a result, there is no sensation in
the burn area.

17. Fourth Degree Burns
• Fourth degree burns can result from
• Prolonged flame contact
• High voltage electrical injury
