Structure of skin. The bulk of the skin consists of two types of tissue: epidermis, the epithelium on the surface; and dermis, the underlying connective tissue. Subcutaneous tissue (a.k.a. hypodermis) attaches the skin to the underlying organs. We will consider it with the skin.
The skin is the largest organ of the body, with a total area of about 20 square feet. The skin protects us from microbes and the elements, helps regulate body temperature, and permits the sensations of touch, heat, and cold. Skin has three layers: 1  The epidermis, the outermost layer of skin, provides a waterproof barrier and creates our skin tone. 2  The dermis, beneath the epidermis, contains tough connective tissue, hair follicles, and sweat glands. 3  The deeper subcutaneous tissue (hypodermis) is made of fat and connective tissue.
