15. Keeping our body in a healthy balance.
Homeostasis
Keeping our body in a healthy balance.

16. Examples of Homeostasis
Dehydration – your body naturally keeps you from dehydrating. When you are losing a lot of water (sweating) your body signals the kidneys to slow down and leave more water in your blood. When you drink an excess of water after exercise signals are then sent to tell the kidneys to speed up.
Your body will slow down its metabolism (the rate that it burns energy) when it is deprived of food.
When you have an infection your body will create more white blood cells, elevate body temperature (fever)
