or:

The Blood Clotting Process

Injury. A small tear in a blood vessel wall (for example, from a cut on the skin or an internal injury) causes bleeding.

Vessel constriction. To control blood loss the blood vessel narrows (called constriction), thus limiting blood flow through the vessel.

Platelet plug. ...
