Study Notes
Positive Feedback in Biological Processes
- Initiates or increases a change in biological processes, such as responding to injury or bleeding.
- Example: Platelets' action in blood clotting when the body is injured.
- Platelets recognize the damaged area through circulating blood and stick together to stop blood loss and patch up the tear.
- The process leads to the formation of a blood clot, minimizing blood loss.
- Positive feedback ends when the blood clot is formed.
- Unlike negative feedback, positive feedback does not maintain a stable, homeostatic condition.
- Instead, it intensifies the change occurring in the body.
