Negative feedback operates when receptors detect deviations, signals are sent to effectors, which then act to counteract the change and restore the normal level.
This card explains that negative feedback works through receptors detecting deviations from normal levels, communicating this to effectors via nervous or hormonal systems, which then counteract the change to return the level to normal.

|---|---|
| Back | Receptors detect when level is too high or too low and the information is commmunicated via nervous system or hormonal system to effectors Effectors respond to counteract the change bring the level back to normal |
