Bleeding disorders
In humans hemostatic failure may result from inherited
or acquired defects of clotting or platelet function.
The usual consequence is persistent bleeding from injuries
that would normally cause little trouble. Some persons
may bleed more easily than normal, perhaps even spontaneously,
as a result of an increased fragility of the blood vessels.
This fragility isnot itself a hemostatic defect but
may be associated with one.
