The skin is composed of layers: The epidermis, the dermis, and the sub-dermal tissue.
The epidermis is the most superficial layer, which works as a mechanical barrier, preventing both potential pathogens from entering the body and fluid from leaving the body.
The dermis contains collagen and elastin fibers, which give elasticity and strength to the skin.
Thermo- and mechanoreceptors, sweat-, sebaceous- and apocrine glands, blood- and lymphatic vessels are located in the dermal layer of the skin.
Below the dermis is the subcutaneous layer which mostly consists of adipose tissue and interstitial fluid.
