Does coagulation involve a positive feedback mechanism or is it negative feedback mechanism?
Homework Answers
Coagulation is a positive feedback mechanism in which it amplifies change and results in more product that is more clotting platelets. This occurs due to clinging of platelets from the injured site or from the injured vessels which results in release of chemical that attracts more platelets. These platelets then piles up with each other and secretes the chemical until clot is formed. As this process enhance the stimulus so it is the positive feedback mechanism.
Negative feedback mechanism is just reverse to positive feedback mechanism that is it reduces the change or inhibits the stimulus. Example: Control of blood sugar by insulin
