| Question | Answer |
|---|---|
| chest pain associated with reduced blood flow to the heart muscle, caused by the destruction of the coronary arteries | angina |
| small artery that empties into capillaries; when it contracts it regulates blood flow to various parts of body | arteriole |
| a vessel w/muscular, elastic walls that conducts blood AWAY from the heart | artery |
| disease characterized by (1) cholesterol deposits blocking the arteries (2) thickening of arterial walls | atherosclerosis |
| electrical activity initiated in sinoatrial node is transmitted to the ventricles via this specialized muscle mass located at base of right atrium | atrioventricular node(AV node) |
| the heart valve that separates each atrium from each ventricl, preventing the backflow of blood into the atria during ventricular contraction. | atrioventricular vale (AV valve) |
| chamber of the heart that receives venous blood and passes it to a ventricle | atrium |
| a fluid consisting of blood cells suspended in plasma | blood |
| process by which platelets, protein fibrin and red blood cells block a damaged surface in or on the body, thus sealing the wound | blood clotting |
| channel that conducts blood thruout body | blood vessel |
| smallest of the blood vessels, it connects arterioles with venules. The walls of capillaries (where nutrients/wastes are exchanged) are only one cell thick. | capillary |
| alternating contraction and relaxation of heart chambers | cardiac cycle |
| type of circulatory system in which blood is always confined w/in heart and vessels | closed circulatory system |
| a type of circulatory system found in some invertebrates which includes an open space (hemocoel) where blood directly bathes body tissues. | open circulatory system |
| an organ of the lymphatic system in which lymphocytes are produced and blood is filtered past lympphocytes and macrophages, which remove foreign particles and aged red blood cells. | spleen |
| hormone produced by the kidneys in response to oxygen deficiency that stimulates the production of red blood cells by the bone marrow. | erythropoietin |
| red blood cell, active in oxygen transport, containing hemoglobin (red pigment) | erythrocyte |
