Front 4

Capillaries

are tiny blood vessels located in the dermis that bring nutrients and oxygen to the skin cells and remove waste and carbon dioxide

Front 5

Cold Sores

refers to a mass of microorganisms. you can see them without a microscope they can have different colors shapes and sizes.

Front 7

Helps hold skin in place. Elastic fibers that allow your skin to stretch and retain it's shape

Front 8

Fat

Back 8

is a layer under the dermis and helps keep the body warm. The thickness depends on it's location

Front 9

Front 10

Virus

Back 10

are so small that they can only be seen with a special microscope called an electron microscope that can magnify hundreds of thousands of times viruses are not cells and need to live in other cells viruses cause many diseases.

Front 11

Pores

Back 11

are tiny openings in the epidermis connected to the sweat glands.

Front 12

SPF

Back 12

stands for sun protection factor. The higher the rating the better protection from the sun. The numbers refers to the number of times loner you can stay out in the sun then normal without burning.

Front 13

sunburn

Back 13

occurs when the cells in the dermis have been damaged by the sun. The redness is a result of increased blood flow to the damaged area.

take the messages from the receptors to the brain.

Fungi

Back 18

are organisms (many are microscopic) that are usually made up of cells that form long skinny strand. most are decomposers they live on dead plant or animal tissues or an animal waste product. examples are mushrooms mold and yeast.

Front 19

Bacteria

Back 19

Single celled microscopic organism that have different shapes. They reproduce by dividing in half many times most of them are decomposers. many of them are beneficial and live in and on our bodes. other types of these microorganisms can cause potentially dangerous diseases.

Front 20

Wart

Back 20

caused by viruses that make cells divide very rapidly; producing rough they can clear up without treatment, but some medications may help and sometimes doctors "burn" them off with laser treatments.

Front 21

Front 23

Dermis

Back 23

is located under the epidermis and is much thicker. it contains blood vessels, glands, nerves, smooth muscle, and hair cells.

Front 24

epidermis

Back 24

Is the surface of the skin the top layer is made of dead cells. the bottom layer is living and active. the cells in the bottom layer divide to replace the ones that die. the epidermis does not have blood vessels.
