Question 14

functions of the integumentary system: protection

a function is protection the epidermis provides

Answer 14

a barrier between the body and outside pathogens such as bacteria

Question 15

functions of the integumentary system: protection

it also prevents the body from

Answer 22

sensory nerve endings that allow the body to detect touch, change in temp, pain

Question 23

functions of the integumentary system: between body and the environment

these nerve endings are found in the skin’s

Answer 23

dermis layer

Question 24

functions of the integumentary system: between body and the environment

skin also produces

Answer 24

vitamin D when ultraviolet light hits the skin

Question 25

homeostasis & the integumentary system

when the body becomes too warm,

Answer 25

sweat glands produce sweat

Question 26

homeostasis & the integumentary system

the evaporation of sweat on the skin creates a

Answer 26

cooling effect

Question 27

homeostasis & the integumentary system

blood vessels in the skin can also dilate when the body is

Answer 27

warm

Question 28

homeostasis & the integumentary system

the dilates blood vessels carry more blood closer to the

Answer 28

skin’s surface and this can appear as flushed cheeks

Question 29

homeostasis & the integumentary system

the blood is then cooled and

Answer 29

returned to the deeper tissue at a cooler temp

Question 30

homeostasis & the integumentary system

if the body is too cold, blood vessels

Answer 30

constrict so that less blood is carried to the skin surface
