Explain the underlying mechanisms for each type of bleeding disorder (e.g. thrombocytopenia, impaired platelet activity, defective Coagulation

bleeding happens when

you dont have enough platelets or cant coagulate properly

thrombocytopenia

not enough platelets to form a platelet plug increasing bleeding

antiplatelet antibodies

immune system mistakenly makes antibodies to destroy platelets

mechnical injury

platelets can be physically damaged or consumed as they move through abnormal conditions in the circulation

impaired platelet activity =

enough platelets but they dont work properly

what interferes with platelets ability to aggregate

asprin and other NSAIDS and renal failure

defective coagulation =

cant properly form fibrin

without fibrin…

the clot is not stable or strong and not held together good

what is needed for normal blood coagulation to make fibrin

vitamin k and calcium
