1. Injury
A small tear in a blood vessel wall (for example, from a cut on the skin or an internal injury) causes bleeding.
2. Vessel constriction
To control blood loss the blood vessel narrows (called constriction), thus limiting blood flow through the vessel.
3. Platelet plug
In response to the injury, tiny cells in the blood called platelets are activated. The platelets stick to one another and to the wound site to form a plug.
4. Fibrin clot
Next, clotting factor proteins trigger production of fibrin, a strong, strand-like substance that forms a fibrin clot, a mesh-like net that keeps the plug firm and stable. The clot strengthens and then dissolves as the wounded blood vessel wall heals.
