Excretion disperses perspiration, which aids in:

• A. Maintaining a healthy temperature
• B. Protecting the skin
• C. Moisturizing the skin
• D. Sending messages to the body's nerve receptors

Answer: (A)

Sweating primarily serves to regulate body temperature. When sweat evaporates from the skin, it absorbs heat, producing a cooling effect that helps keep the body's temperature in a safe, healthy range during heat, exercise, or illness. While perspiration can contribute a little to skin moisture and cleansing, its main role is thermoregulation, not protecting the skin, moisturizing, or sending signals to nerve receptors.
