Abstract
This chapter focuses on the skin, which is the largest organ in the body, covering the entire outer surface of the body. Together with the hair, nails, and glands, the skin forms an integumentary system. The chapter points out that the thickest skin is found in areas that are subject to abrasion such as the soles of the feet, while the thinnest is found around the eyes. The chapter looks at how a great deal of useful information regarding a person's age, nutritional status, hydration status, circulation, and emotional state can be obtained by careful inspection of the skin. Furthermore, the characteristics and colour of a person's skin can sometimes yield information regarding certain disease states, particularly in those whose skin is pale.
