& touch

7. Functions of the Integumentary System
Forms a protective covering over the body
Maintains homeostasis—regulates body temperature
Excretes wastes—
sodium chloride (salt),
water, urea
Sensory organ—nerve
endings are sensitive
to temperature,
pressure, & touch
Produces vitamin D
in the epidermis using sunlight

8. Which is NOT a function of the integumentary system?
To prevent substances from entering the body
To help keep body temperature stable
To remove wastes from the body

9. Layers of Skin Epidermis = surface layer Cells on top are dead
New cells are
constantly
produced at the
bottom
Cells produce
melanin
(pigment that
gives you skin
color)

10. Layers of Skin Dermis = layer under epidermis Thicker than epidermis
Contains blood
vessels, nerves,
oil and sweat
glands
Fat cells stored
under the dermis

11. Which part of the skin makes new skin cells?
Epidermis
Dermis
Fat cells
Sweat glands 9 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30

12. On the sheet of paper: Describe the function of the integumentary system You must write at least 3 sentences Then crumble your paper. 3. Wait for me to say go & toss the paper in the classroom. 4. Pick up a paper and read the function. 5. Correct any mistakes and this is your ticket out the door.
