Skin is the largest organ, covering our bodies.
Skin regulates body temperature, helps respiration by means of gas exchange and helps excretion by sweating. Skin also protects the body from external effects. “Skin is also associated with immunity processes and it has metabolic functions.”
Skin is composed of three layers:
- Epidermis (outermost layer)
- Dermis (layer under the epidermis)
- Subcutis (a part of dermis)
- It is the layer that protects sub layers of the skin.
- This layer does not have blood vessels and nerves.
- Outer part of the epidermis is composed of dead cells.
- It contains cells that define the color of the skin.
- It protects the skin from the dangerous rays of light.
- It is thicker than the epidermis and composed of living cells.
- It has blood vessels, nerves, sweat glands, sebaceous glands, hair follicles and sensory receptors.
- “It provides elasticity of the skin and contains thin elastic fibers”.
“Actually there are no borders between dermis and subcutis; wherein the thickness and transition properties of each part depends on age, gender, eating habits, life conditions and their location on the body.”
It protects the body from hits and impacts besides preventing heat loss from the body.
Sweat glands are located here, therefore it helps excretion.
