7. Thermoregulation is a negative feedback control system in the body. Which of the following statements correctly explains how thermoregulation works? A. In hot temperatures, the body maintains homeostasis by activating the sweat glands to release heat, which cools your skin as it evaporates. B. When the body is hot the blood vessels under your skin get wider. This increases blood flow to your skin where it is cooler C. When the body is cold the blood vessels under your skin become narrower. This decreases blood flow to your skin, retaining heat near the warm inner body. D. All of the above.
