BIOL 208 Lecture Notes - Lecture 8: Atherosclerosis, Warfarin, Streptokinase
Document Summary
Canned statement ischemia - condition where there is a partial blockage of blood ow and where the tissues, due to a lack of suf cient o2, are hurting and stressed, but not dead as in necrosis. Intravascular clotting - two potential causes of unwanted clotting: structural - any condition that roughens the walls of the blood vessels. Slowly owing blood - sitting for long amounts of time slows down venous return. Venous stasis - when the valves that stop blood from moving in the wrong direction in deep veins close and cause swelling: manufactured anticoagulants - Warfarin & dicumoral (coumadin) - block action of vitamin k, therefore inhibiting proper synthesis of coagulants (used in rat poison to induce hemorrhaging) Tpa - injected into heart to dissolve blood clots. Streptokinase - bacterial enzyme that dissolves blood clots: shock = massive drop in blood pressure caused by:
