The process of blood clotting involves a positive feedback mechanism as the formation of a clot triggers the release of more clotting factors, leading to more clotting. This positive feedback can become a vicious cycle and continue until the clotting is stopped by external factors, such as anti-coagulants or physical intervention. However, it does not contain its own brake and requires external factors to halt the process.
