PRACTICE LAB
Build a feedback loop
Practice question
Order a negative-feedback response to a rise in body temperature.
The last step has to feed back. Stopping at “sweat” names an output and misses the system.
The lower temperature is detected, and the sweating response is reduced.
Heat is lost and body temperature falls.
The coordinator increases sweating and vasodilation.
Thermoreceptors detect the rise.
Body temperature rises above the set point.
