Negative feedback - Higher tier only
Homeostatic control is achieved using Mechanism to lower raised levels of something, and to raise reduced levels of something.:
- if the level of something rises, control systems reduce it again
- if the level of something falls, control systems raise it again
Control of blood glucose
The control of blood glucose is an example of negative feedback.
Following a meal, blood sugar will rise above normal levels
Following exercise, the blood sugar level will decrease below normal levels
