Study Notes

Skin Functions

Skin is responsible for physical appearance.
It protects the body from external factors.
It regulates body temperature.
It allows the body to experience sensations.
Skin helps conserve bodily fluids.

Skin Structure

Dermis

Contains collagen and elastin, providing structural support and elasticity.
Houses blood and lymphatic vessels for nutrient delivery and waste removal.
Contains nerves for sensory perception.
Includes epidermal/dermal appendages: hair follicles and sweat glands.

Epidermis

Lacks blood vessels (avascular).
Composed of epithelial cells.
Contains melanocytes for pigment production (skin color).

Burn Complications

Chemical Burns

Chemical burns, like hydrochloric acid, continue damaging tissues until diluted.

Electrical Burns

Electrical burns, such as those from lightning, can lead to cardiac arrhythmias, respiratory failure, and neurological damage.

Calculating Burn Size (TBSA)

The "Rule of Nines" is used to estimate the total body surface area (TBSA) affected by burns.
