Skin Diseases
The skin is the largest organ of the body. It forms a protective barrier against germs and other organisms, and keeps the inside of our body protected from external environment. Skin also helps to maintain a constant body temperature. Human skin is only about 0.07 inches (2 mm) thick. |

| Skin is made up of two layers that cover a third fatty layer. The outer layer is called the epidermis; it is a tough protective layer that contains melanin, which protects against the rays of the sun and gives the skin its color. The second layer located under the epidermis is called the dermis; it contains nerve endings, sweat glands, oil glands, and hair follicles. Under these two skin layers is a fatty layer of subcutaneous tissue. On average, an adult has from 18-20 square feet (about 2 square meters) of skin, which weighs about 6 pounds (2.7 kg). | ||
