Nervous system
Which function of sweat is emphasized in the material?
Providing pigmentation
Excreting waste products
Producing antibodies
Increasing nerve sensitivity
Which change due to aging is correctly paired with its description?
Increase in collagen leading to thicker skin
Loss of elastic fibers resulting in decreased elasticity
Greater protective fatty layer making skin less fragile
Hair becomes thicker and darker overall
First-degree burns primarily affect which skin layer?
Epidermis
Dermis
Subcutaneous tissue
All skin layers and underlying tissue
Which statement best distinguishes second-degree from third-degree burns?
Second-degree burns cause redness without pain; third-degree burns cause pain only
Second-degree burns affect the dermis and cause blistering; third-degree burns affect all skin layers and may char skin
Second-degree burns affect the epidermis; third-degree burns affect only the dermis
Second-degree burns involve muscle and bone; third-degree burns affect only skin
Which is a risk factor for cellulitis listed in the material?

Fungal infections (tinea) commonly occur in what type of body area?
Dry areas exposed to sun
Moist areas of the body
Areas with thick fatty layers
Scar tissue only
What happens to pressure injury risk when blood circulation to the skin is reduced?
Risk decreases due to less metabolic activity
Risk remains unchanged
Risk increases due to higher chance of skin breakdown
Risk increases only in the epidermis
Stage II pressure ulcers involve partial-thickness skin loss. Which layers are affected at this stage?
Only the epidermis
Epidermis and dermis

Which function of the integumentary system is most directly supported by sweat gland activity during exercise?
Protection from UV radiation
Thermoregulation
Synthesis of red blood cells
Production of sebum
Which statement best differentiates apocrine from eccrine sweat glands?
Apocrine glands are widely distributed and primarily aid in cooling; eccrine glands activate during puberty.
Apocrine glands secrete odorless watery sweat; eccrine glands produce thicker, protein-rich secretions.
Apocrine glands are localized in areas like axillae and are associated with scent; eccrine glands are numerous and produce watery sweat for cooling.
Apocrine glands secrete sebum; eccrine glands secrete melanin.
