All about skin and its different layers

Skin is the largest part of our body that contains water, fats, proteins, and minerals. Skin work as a protection shield that prevents our body from germs and regulates the right body temperature. The nerves present in the skin allow you to feel sensations like hot and cold. There are three layers of tissues that build your skin including the epidermis, dermis, and Hypodermis.

Role of the top layer of the skin (epidermis)

 It is a top layer of skin that you see and touch. The skin cells contain keratin which is a type of protein used to develop skin cells along with other proteins. The epidermis work as:-

  • The protective layer that keeps the bacteria and germs away from entering the body and bloodstream that leads to infections. It also prevents your skin from rain, sun, and other elements.
  • It builds the new skin cells and replaces around 40,000 old skin cells that cover your body. The new skin generates in every 30 days.
  • Langerhans cells are present in the epidermis and part of the immune system that fights against germs and infections.
  • Melanin is also present in the epidermis layer that gives color to your skin. The melanin amount determines the color of your eyes, hair, and skin.

Role of the middle layer of skin (dermis)

  • This layer is made by 90 percent of skin thickness and contains collagen protein to make the skin cells stronger and resilient. It also helps your skin to get stretched and regain its shape.
  • The roots of the hair are attached to the dermis
  • Nerves present in the dermis will allow you to feel too hot, itchy, or super soft
  • Oil glands found in the dermis will help to keep your skin soft and smooth. It also helps in preventing your skin from absorbing too much water while swimming.
  • Dermis is responsible for releasing the sweat from the skin pores and help in maintaining the body temperature.

Role of hypodermis (bottom layer)

It is a fatty layer of the skin. The hypodermis works as:-

  • Cushion for bone and muscle: – Fat present in the hypodermis layer prevent your bones and muscles from injuries.
  • Connect the tissues: – It works well in connecting the skin layer to muscles and bones.
  • Regulate body temperature: – fat present in this layer also keep you to get too cold or hot.
