During the initiation stage, platelets are activated and release chemicals that attract more platelets to the site of injury. This forms a platelet plug that helps to stop bleeding. During the propagation stage, a series of enzymes are activated that convert fibrinogen, a soluble protein in the blood, into insoluble fibrin strands. These fibrin strands form a mesh-like structure that traps red and white blood cells and platelets, creating a blood clot. Finally, during the termination stage, the blood clot is dissolved by a group of enzymes called fibrinolytic enzymes. This process helps to prevent the formation of excessive blood clots that could block blood vessels and cause serious health problems. Overall, blood coagulation is a critical process that helps to prevent excessive bleeding and promote healing in the body.
