Hemophilia
Normal Clotting
Response to
vessle injury
1.
Vasoconstriction to reduce blood flow
2. Platelet
plug formation (von willebrand factor binds damaged vessle and platelets)
3.
Activation of clotting cascade with generation of fibrin clot formation
4.
Fibrinlysis (clot breakdown)
Clotting Cascade
Normally
the ingredients, called factors, act like a row of dominoes toppling against
each other to create a chain reaction.
If one of the factors is missing this chain reaction cannot proceed.
