When body temperature increases above the normal range, thermoreceptors in the skin and hypothalamus detect the increase in body temperature. The heat-loss center of the hypothalamus is activated, which sends signals to blood vessels and sweat glands. In response, blood vessels in the skin dilate and sweat glands release sweat.
Determine the part of this negative feedback loop that serves as the effector(s).
