=Introduction=

Ever wanted to know what kind of functions skin cells own. The epidermis is very important to your body so imagine a tornado going towards a Home Depot store and then people saying “oh no we are all gonna die” everybody in the store shrek's as the tornado comes closer and closer. But little did they know that the wall in the Home Depot is made to last long and powerful storms. Like your epidermis or the first layer of your skin protects your body. Well what happens when the epidermis is scratched or cut. Or when something like a tattoo goes into your skin what happens. If you want to find out how this happens or why? Keep reading on to find out.

=Why is the Epidermis Important?=

The Epidermis is the first layer of your skin. It protects us from micro organisms that can sicken us and even cause death. It also excretes salt, water and organic wastes away. It also blocks out UV rays from the sun and regulates our body temperature. Imagine the Epidermis as a wall on a building and it is raining outside. The rain is the UV rays from the sun and the heat inside the building is our body temperature. The wall on a building keeps the people inside of it warm (body temp.) and the rain outside of the inside of the building (UV rays). The epidermis protects the inside and outside of the body like a wall does. Also picture this. A tennager with a house and no power. So he puts solar panels on the house. The epidermis also captures a lot of vitamin D which makes us happy. (why we aren't as happy in the winter than in the summer) The solar panels absorb the sunlight, which turns on the Wi-fi and the TV in the house. So know the teen is happy. But without sunlight the teen is sad (like in the winter) because he has no electricity. To recap, the epidermis is important in many ways such as keeping microorganisms away and regulating our body temp. like a wall on a building. =How does the Epidermis Work?= The epidermis is the first layer or top layer of skin on your body. There are only sweat glands in the epidermis no blood vessels and no nerves. That is why shallow cuts don’t hurt or bleed as much or at all rather than deep cuts that go into your dermis which is the second layer of skin. Imagine again a wall. The wall has 3 layers like the skin cells have. The outside layer is the layer that keeps everything out. That's why on a house small chips or cracks don’t let in rain or cold air. The middle layer where all the power cables are (the nerves and blood vessels. Lastly, the layer that is closest to the inside of the body the painted area in your house that has all the plugs and switches like where the blood vessels and nerves connect inside your body. In final, the Epidermis does not bleed because there are no nerves and blood vessels in that layer. =How do Tattos Impact Skin Functions?=

When tattoos are put into the skin, they are inserted in the dermis or the middle layer of skin. Over time the tattoo becomes faded. This is because the ink becomes separated then the white blood cells take away the loose ink. So basically it just acts normal to it. The skin does it’s normal job and the white blood cells take the bad loose ink away.

=Conclusions= In final, skin cells are very important to the body in many ways. For example, the functions of the skin protect us like why the epidermis is important. Another example is how does the epidermis works. Lastly, I found out if tattoos impacted skin cells. This all showed why and how skin is important in many different ways. =References= Works Cited “Diagram of Epidermis.” Debgroup.com. N.p., n.d. Web. 1 Mar. 2016. .
