Which of the following describes the sensation function of the skin?

  1. Responding to touch, pain, cold, heat, and pressure

  2. Regulating internal body temperature

  3. Detoxifying the body by excreting excess water

  4. Absorbing water and essential nutrients

The correct answer is: Responding to touch, pain, cold, heat, and pressure

The correct answer is A. The sensation function of the skin involves responding to touch, pain, cold, heat, and pressure. The skin contains sensory receptors that detect these sensations and send signals to the brain to interpret them. This function helps us navigate our environment and protect ourselves from potential harm. Choices B, C, and D are incorrect: B. Regulating internal body temperature is related to the thermoregulation function of the skin, not the sensation function. C. Detoxifying the body by excreting excess water is not a primary function of the skin. D. Absorbing water and essential nutrients is part of the absorption function of the skin, not the sensation function.
