Arterioscelorosis - Answer Any of a number of proliferation and degenerative changes in the arteries
leading to their decreased elasticity.
Hemostasis - Answer stoppage of bleeding
Endocardium - Answer Endothelial membrane that lines the interior of the heart
Thrombin - Answer Enzyme that induces clotting by converting fibrinogen to fibrin
