The Skin's Structure
The skin is the largest human organ. It covers between 1.5 and 2 m² and accounts for about one sixth of total body weight.
The skin consists of three functional layers:
In these layers are found the epidermal appendages: nails, hair and glands (i). The skin performs various functions such as temperature regulation and insulation, energy storage, sensory perception and protection from environmental influences (i) such as fungi, bacteria and (UV) radiation.
