System)
the skin - correct answer ✔provide barrier
regulates body temperature
synthesizes vitamin d
allows sensory perception
provides nonverbal communication
provides identity
allows wound repair
allows excretion and metabolic waste
provides barrier - correct answer ✔protecting the body from
a. injury secondary to mechanical, chemical, thermal, and ultraviolet (UV) light
sources.
b. penetration by microorganisms.
c. loss of water and electrolytes, thereby preventing dehydration
regulates body temperature - correct answer ✔by allowing heat dissipation
through sweat glands and heat storage through subcutaneous insulation.
synthesizes vitamin d - correct answer ✔from cholesterol by the action of UV
light
, allows sensory perception - correct answer ✔via end sensory organs for
touch, pain, temperature, and pressure.
provides nonverbal communication - correct answer ✔such as posture, facial
movements, or vasomotor responses such as blushing.
provides identity - correct answer ✔thru skin colors and facial features
allows wound repair - correct answer ✔thru cell replacement of surface
injuries
allows excretion and metabolic waste - correct answer ✔such as
electrolytes, minerals, sugar, or uric acid.
epidermis - correct answer ✔is thin, devoid of blood vessels, and itself
divided into two layers: an outer horny layer of dead keratinized cells and an
inner cellular layer where both melanin and keratin are formed. Migration from
the inner layer to the top layer takes approximately 1 month.
dermis - correct answer ✔second layer of skin, holding blood vessels, nerve
endings, sweat glands, and hair follicles
subcutaneous layer - correct answer ✔connective and adipose tissue layer
just under the dermis
melanin - correct answer ✔dark brown to black pigment contained in
melanocytes
