skin, nails, hair follicles, and sweat glands.
bones and muscles
only one type of tissue
the epidermis, dermis, and subcutaneous layer

they divide continually
their supply of nutrients improves
they die
they become dermal cells

the hypodermis
the nail bed
a sebaceous gland
a hair follicle
Sebaceous glands secrete
sweat in the armpits
fat globules that much with cellular debris, forming sebum

are in the blood
are secreted from modified sweat glands
are secreted from modified sebaceous glands
are not secretions
Body heat is lost primarily by...
conduction
convection
evaporation
radiation
Which if the following is a normal response to excessive loss of body heat in a cold environment?
Dermal blood vessels constrict
Smooth muscles relax
Sweat glands become active
Dermal blood vessels dilate
Sweat cools the body by...

conduction
radiation
evaporation
A warm surface loses heat to the air molecules continuously circulating over it by...
convection
evaporation
radiation
conduction
Hypothermia is...
a lowered body temperature
associated with exercising vigorously in the heat
a form of hair loss
accommodated by fever
Individuals at elevated risk for hypothermia include...
the very old and the very young
homeless people exposed to the outdoors
very thin people
all of the answers choices are correct
Inflammation makes skin
cool and clammy
secrete abundant antibodies
red, swollen and painful to touch
peel off
Inflammation
is a type of infection
is an abnormal response to injury or stress
is a normal response to stress or injury
is a result or exposure to very low temperatures
Which of the following happens first after a scab forms?
the scrap sloughs off
phagocytosis cells remove dead material
blood vessels send out new branches under the scab
fibroblasts from the wound edge form new collagenous fibers
A burn affecting only the epidermis is a
deep partial-thickness burn
third-degree burn
second-degree burn
superficial partial-thickness burn
An autograft covers an injured area of skin with
skin from an uninjured region of the patient’s body
skin from a skin bank
a skin substitute, such as an artificial membrane
skin from a person other then the patient
In treating a burn patient, the “rule of nines” is used to estimate the
depth of the burn
surface area of the burn
degree and source of the burn
type of scar that will form
The skin wrinkles with age because...
fat is lost from the subcutaneous layer and the dermis shrinks
epidermal calls undergo a burst of cell division
the number of sweat glands diminishes
collagen degrades in the subcutaneous layer as the epidermis shrinks
