The skin is one of the largest and heaviest organ of the body. In an average adult, the skin covers about 2 square meters (22 square feet), weights 4.5-5 kg (10-11 lb) and varies in thickness (1.5 to 4.0 mm) depending on what part of the body it covers.
The skin covers all of the exposed surface of the body and is continuous with the mucous membranes lining openings into the body surface, such as those of the digestive, respiratory and urogenital systems.
Beneath the dermis is the hypodermis (=subcutaneous tissue = superficial fascia) which anchors the skin loosely to underlying tissues (mainly muscles). The hypodermis is NOT part of the skin
