Anatomy and Physiology: Integumentary System

Question 1

Skin

Answer 1

protection
water balance
temperature regulation
excretion
shock absorption

Question 2

skin and temperature regulation

Answer 2

blood vessels in the skin can dilate (increase) to carry more blood to the skin. Heat radiates to the body

blood vessle can constrict to prevent heat loss

sweat glands found in the skin produce perspiration, will evaporate and help cool the body

fat layer beneath the skin serves as a theramal insulator

Question 3

epidermis

Answer 3

composed of four layers (strata) everywhere

at the palms of the hands and soles of the feet there are 5

outermost layers are composed of dead skill cells

living cells and pigment granular are deeper

no blood vessels or nerves are in this layer

Question 4

Dermis

Answer 4

layer os skin below the epidermis, right in blood vessels, nerves and specialized structures-
-sweat glands
- sebaceous (oil) glands
- hair follicles
-nerve endngs

Question 5

subcutaneous layers

Answer 5

layers of fat and soft tissue below the dermis
- shock absorption and insulation are the major functions of this layer
