The outermost layer of the human body, the skin, acts as the body’s first barrier against foreign particles. It is the largest organ in the human body and acts as a barrier between the external and internal environment. The skin consists of different layers, cells and tissues.
The human skin plays an important role in overall health and well-being, which is divided into three main areas: epidermis, dermis and subcutaneous tissue.
Here in this article, we will discuss the difference between skin and skin. The main difference between skin and skin lies in their structure.
What is Epidermis?
The epidermis is the topmost layer of the skin. The thickness varies from 0.05 to 1.5 mm. The epidermis consists of many cells. Keratinocyte cells are mainly found in the epidermal layer of the skin.
Another type of cell, called melanocytes, consists of colored corn. Melanin is the substance that gives the skin its color. The third type of clamp available at this level is Langerhans; These cells interact with white blood cells and act as a barrier to the immune system.
What is Dermis?
After the dermis, the next middle layer is the skin. The thickness varies from 0.3 to 3.0 mm. This layer consists of connectors.
This layer contains some important components such as strong protein collagen and elastic protein fibers. In addition, this layer contains various antibodies and protective properties of the skin.
Difference Between Epidermis and Dermis
| Epidermis | Dermis |
| The outermost layer of cells that covers the body of an organism | A layer of living cells below the epidermis consisting of nerve endings, blood vessels, sweat glands and hair follicles |
| It doesn’t contain blood vessels | Comprises a thin network of vessels known as capillaries |
| No nerves present in the epidermis | Comprises nerves that conduct nerve impulses from the central nervous system toward the brain. The sensation of pain originates from the open nerve ending of this layer. |
| Obtains essential nutrients and oxygen by diffusion from the dermis | Obtains oxygen and nutrients from the blood capillaries |
