GENERAL HISTOLOGY

Detailed explanation-1: -The skin is the body’s largest organ. It measures about 1.5-2 m2 in adults and weighs about 15 per cent of total body weight.

Detailed explanation-2: -Skin accounts for about 15% of your body weight. The average adult has approximately 21 square feet of skin, which weighs 9 lbs and contains more than 11 miles of blood vessels. The average person has about 300 million skin cells.

Detailed explanation-3: -Dermis, the structural foundation of skin, accounts for about 90 percent of its weight. The primary cell type in the dermis are fibroblasts, which produce the extracellular structural proteins, collagen, elastin (Figure 11.5), as well as GAGs, the major water holding components of the dermis.
