Three Layers of Skin: The Importance of Each Human Skin Layer The human skin is the largest organ on/in the body.
Most people don't think of the skin as an organ like they would a heart, brain, lungs, liver and more.
However, the skin is essentially made up of a variety of tissues and within these tissues are cells, all of which are very important for body care.
Think of the skin like a home's roof; it's a vital part of the human body as it keeps all the fluids inside the body and controls the release of waste.
The internal organs are safe from possible environmental harm such as the bacteria, injury, light and sun.
The skin has several layers to it and because people don't see them, they are often not thought about.
People tend to worry every day about the wrinkles and acne they are getting, not taking into consideration the layers underneath the skin have plenty to do with these things.
If a person were to break down the skin into layers, they would see three different skin layers.
They are: - Epidermis - Dermis - Hypodermis Layer 1 - Epidermis The epidermis is the outer skin layer.
This is the one people see.
The epidermis covers the body, is made of closely woven connective tissue of differing thickness and also consists of three layers.
The feet have more skin than the eye.
The epidermis is a barrier to keep bad things out and keep the good things in.
The epidermis' top layer is always shedding.
This is the layer that will make sure fluids stay inside the body while making sure that no dangers creep their way in.
The majority of this layer has thousands of minute pores and hair shafts though this cannot easily be seen by the naked eye.
The bottom layer continually generates new skin to replace the skin that's being shed.
This is the skin layer that has melanin, which is responsible for giving the skin its color (or lack thereof) and making sure the body on the inside has sun protection so it is not harmed.
Layer 2 - Dermis The dermis is the middle skin layer that has lots of activity within it.
Within the dermis are the blood vessels, collagen glands, hair follicles, lymph vessels, nerve tissues and sweat glands.
Blood vessels will supply nutrients.
The nerve tissues allow the skin to feel good and bad touches.
When the muscles tissues are active, they cause the person to have goose bumps, whether they occur in fear or from the cold.
The dermis can trap bacteria that managed to get past the epidermis.
Layer 3 - Hypodermis (Subcutis Layer) The inside skin layer regulates the body temperature.
This layer has the insulating fat and collagen, which is how people stay warm.
It also acts as a shock absorber to protect the body from being injured.
This layer of skin is also called adipose tissue.
