Describe the events that occur in the clotting of blood by choosing the correct sequence of statements that outlines the process. 1. Platelets and injured tissue release prothrombin activator. 2. The activated fragments join end-to-end, forming long threads. 3. Platelets clump at the sight of puncture and partially seal the leak. 4. Fibrin threads wind around the platelet plug in the damaged area and provide a framework for the clot. 5. Thrombin, acting as an enzyme, severs two amino acid chains (activated fragments) from each fibrinogen molecule. 6. Prothrombin activator converts prothrombin to thrombin. 7. Red blood cells are trapped within the fibrin framework forming a clot.
