Do You Know About Skin ???
Skin is an organ you probably don’t think about much, but its extremely important. It protects and covers the muscles, bones, and other organs and holds them together. It also keeps our bodies at the right temperature, protects our bodies from harm, and gives us the sense of touch.(Do You Know About Skin)
- Layers of the Skin
Your skin is made up of three layers: the epidermis, dermis, and subcutaneous fat. Let’s take a look at each layer.
The epidermis is the part of the skin that you can see. It’s thin in some places but thicker in other places. This layer of skin is responsible for making new skin cells, giving skin its color, and protecting your body. New skin cells form at the bottom of the epidermis, and they take about 2 weeks to a month to move to the top. During this time, older cells on the top die and rise to the surface of your skin, where they eventually flake off.
The dermis is beneath the epidermis and contains nerve endings, blood vessels, oil glands, and sweat glands. Nerve endings work with your nervous system to send messages to the brain about what you touch and feel. For instance, your nerve endings might alert the brain that a surface feels hot. Using this information, the brain sends a message telling you to move your hand. The tiny blood vessels in your dermis bring oxygen and nutrients to your skin cells to keep them healthy.
- Subcutaneous Fat
The bottom layer is subcutaneous fat. As you might guess, it’s made up mostly of fat. It helps keep your body warm and absorbs shocks, like if you bump into
something hard or fall down. Hair follicles have their roots in the subcutaneous layer, and they rise up through the dermis.
