When these foreign invaders enter the body, the immune system recognizes them as threats and mounts a response to eliminate them. Additionally, the immune system can also be activated by damaged cells, allergens, and other harmful substances. Once activated, the immune system produces antibodies, white blood cells, and other immune cells to fight off the threat and protect the body from infection and disease. **

The component that activates the compressor of a refrigerator is the thermostat. The thermostat monitors the temperature inside the refrigerator and when it detects that the temperature has risen above the set level, it sends a signal to the compressor to start running.
