process of clotting blood
The body stops this blood loss through a complex clotting process called hemostasis. During hemostasis, the injured blood vessel constricts to reduce blood flow, platelets adhere to the injury site and clump (aggregate) together to form a loose platelet plug, and the coagulation cascade is initiated.
When a blood vessel is injured, the coagulation cascade is initiated and each coagulation factor is activated in a specific order to lead to the formation of the blood clot. Coagulation factors are identified with Roman numerals (e.g. factor I or FI). Watch Dr. Roshni Kulkarniâs interactive animation.
