IV). Maintaining Homeostasis
A). Definition
Homeostasis :
B). Homeostatic Control Mechanisms
control center > receptor sensor effector > stimulus response (input) (output)
1). Control Center
2). Receptor
3). Effector
causes a response or an output
C). Types of Control
1). Negative Feedback
When the output increases Ç it feedbacks into the system and inhibits input È . Thus lowering the output.
2). Positive Feedback
An increase output Ç results in the input increasing Çwhich increases the output.
