Mechanisms

Negative Feedback

• Regulate physiological processes by stopping cellular response

• Causes the body system to return to its normal state thus re-establishing homeostasis

• MOST COMMON

• EX: air conditioning/heating

Positive Feedback

• Initiate and amplify biological processes in the body system

• Used to produce large systemic changes to reestablish homeostasis

• Keep pushing you past homeostasis to reach a further goal

• EX: birth, food poisoning
