Q
Functions of integumentary system
A
- skin protects body from bacteria entering the body, 2. from water loss and damaging effects of UV light, 3. regulation of body temp and synthesis of vitamin D

Q
epidermis
A
outer layer of skin
4
Q

A
layer of epidermis, the scleroprotein component of the horny, or cornified
5
Q

color, or pigmentation, of skin
6
Q

7
Q

A
sweat glands, tiny, coiled, tubular structures that emerge through pores on the skin’s surface and secrete sweat
8
Q

originate in the epidermis. Nails are found on the upper surface of the ends of the fingers and toes. The white area at the base of the nail is called the lunula, or moon.
