The ability to maintain body temperature within a certain range is ...

• thermodynamics

• thermoregulation

• thermostat

• thermometer

The tendency of an organism to maintain a balanced state in order to stay healthy.

• Stimuli

• Response

• Tropism

• Homestasis

When glucose levels in the blood rise, your brain sends a signal to your pancreas. The pancreas releases insulin, which opens channels in cell membranes to allow glucose to enter the cell, lowering blood sugar levels. 

• Positive Feedback Response

• Negative Feedback Loop
