thrombocytes | platelets; smallest formed elements of the blood, plays an important role in clotting; accumulates on injury and becomes sticky to prevent bleeding |
thrombus | an attached blood clot to the interior wall of an artery or vein |
tissue plasminogen activator | thrombolytic that is administered to some patients who are having a heart attack or stroke; if administered within a few hours after symptoms begin, this medication can dissolve the damaging blood clots |
