Which of the following statements is incorrect?
The skin is merely a covering of the body, involved only in protection
The skin is the outermost covering of the body. However, it is not just a simple covering - it is a vital part of a person's body. The skin is considered to be the largest organ of the human body. It is also the most apparent feature that indicates a person's approximate age - wrinkled in an elderly person, healthy looking in a young person, and tender in a baby. There are also various structures (e.g., nails, hair etc.) and glands (e.g., sweat glands, sebaceous glands etc.) that are derived from the skin. Thus, protection is just one among the various functions of the skin.
