Give other examples of disturbances in the internal environment that can act as a stimulus to a feedback mechanism.
When we feel dehydrated, we get thirsty, which is an example of a disturbance in the internal environment. Our negative feedback mechanism handles this disturbance. Our receptors detect this stimulus and release signals to feel thirst, which makes us respond by increasing our water intake.
Another example would be our body temperature. When we have a fever, sensors will detect this temperature change then they will send signals to the brain, where our temperature-regulatory control center is. Our control center will send signals to our sweat glands that will help us regulate our body temperature.
