Composed in the first place of the throw together, it protects, nourishes, insulates, and cushions. Accessory structures within this system include hair, nails, and real exocrine glands. Accounting for approximately 7 percent of the body, the cutis is t he largest and heaviest organ of the body (Cohen & Taylor, 2005). Without it, bacterium would attack an idiosyncratic immediately, or death from heat and vaporization would occur. Chronological maturement affects biochemical changes to trim. The supportive fibers of collagen and elastin break down. Skin does not retain as much moisture as it formerly did. The skins ability to fight infection, feel sensations, and regulate body temperature alike diminishes. ok lines around the eyes, deepened expression lines at the corners of the mouth and across the forehead, and drooping skin are some visible signs of aging skin. In addition, hair may become coarser, gradually move lynchpin color, or begin to thin, and nails become more brittle with age. Photoaging of the skin is far more damaging than age alone. Over the years, sun exposure causes fine and coarse wrinkles; baggy skin with a yellow, leathery appearance; and dry, scaly skin.
