To understand the concepts of a wound and wound healing, we must examine the skin and its pathophysiology, as well as its unique structures and functions. Skin care and wound management must be grounded in a comprehensive knowledge base of the structure and functions of the skin. The skin is the largest organ of the body, covering approximately 18 square feet and weighing about 12 pounds, or up to 15% of total adult body weight. It requires one-third of an individual’s circulating blood volume to sustain it. Normal surface skin temperature is 92 degrees, compared with a core body temperature average of 98.6 degrees.
