Which of the following is the correct function of the skin's thermoregulation process?

  1. Detoxifies the body by excreting excess water

  2. Maintains an average internal temperature of 98.6°F

  3. Protects the body from external factors

  4. Responds to touch, pain, cold, heat, and pressure

The correct answer is: Detoxifies the body by excreting excess water

The correct function of the skin's thermoregulation process is to regulate body temperature by excreting excess water through sweat glands. This helps cool the body down when it is overheated. Option A correctly describes this process. Options B, C, and D are not related to the skin's thermoregulation function. Option B mentions maintaining an average internal temperature of 98.6°F, which is the function of the body's internal mechanisms and not solely the skin. Option C refers to the skin's protective function from external factors, while Option D mentions the skin's sensory response to touch, pain, cold, heat, and pressure, which are different functions of the skin.
