The clotting mechanism is broken into 2 stages:
Primary hemostasis: Formation of a weak platelet plug
Secondary hemostasis: Stabilizing the weak platelet plug into a clot by the fibrin network

Blood clotting is the mechanism by which blood oozing out from the injury stop suddenly to prevent the loss.
Platelets are the non nucleated blood cells which bring about clotting of the blood. Platelets are special irregular cells present in the blood. These are also called as thrombocytes as they lyse and release thromboplastin which brings about clotting of blood. Presence of calcium is also necessary for blood clotting. Platelets also aggregate in large amounts to form a plug at the injury preventing the blood loss. Blood clotting is very essential for an individual to prevent the loss of blood and later anaemia.
