Terms | Definitions |
|---|---|
 Mediastinum | area between the lungs that contains the heart, aorta, trachea, lymph nodes, thymus gland, esophagus, and bronchial tubes |
| Myocardium | the middle muscular layer of the heart wall |
| Pericardium | a double-layered serous membrane that surrounds the heart |
| Myocardium | thick middle muscle layer of the heart |
| Endocardium | inner layer of the heart |
| Arteries | the vessels that lead away from the heart |
| Veins | thinner walled vessels compared to arteries. They move deoxygenated blood toward the heart from the tissues |
| Capillaries | the smallest vessels that form the point of exchange for oxygen |
| Aneurysm | ballooning of a weakened portion of an arterial wall |
| AAA | abdominal aortic aneurysm |
| Arteriosclerosis | hardening of the arteries |
| Peripheral arterial occlusive disease | also known as peripheral artery disease, is an example of a peripheral vascular disease caused by atheroscleroisis |
| PAD | peripheral artery disease |
| Chronic venous insufficiency | a condition in which venous circulation is inadequate due to partial vein blockage or leakage of venous valves |
| Phlebitis | inflammation of a vein (usually in the legs) |
| Varicose veins | abnormally swollen, twisted veins with defective valves, most often seen in the legs |
| varicosities | Varicose veins, visibly prominent, dilated & twisted veins, usually in lower extremities |
| Thromboses | The formation, presence, or development of a thrombus |
| Thrombus | a fibrinous clot that forms in and obstructs a blood vessel, or that forms in one of the chambers of the heart |
| Thrombotic occlusion | the blocking of an artery by a thrombus |
| Deep vein thrombosis | formation of a clot in a deep vein of the body, occurring most often in the femoral and iliac veins |
| DVT | deep vein thrombosis |
| Embolus- | an abnormal particle (e.g. an air bubble or part of a clot) circulating in the blood |
| tricuspid valve | valve(cusps are flaps of the valves): between right atrium and right ventricle |
| pulmonary semilunar valve | between right ventricle and pulmonary artery |
| mitral valve | between left atrium and the left ventricle |
| aortic semilunar valve | between left atrium and aorta |
| diastole | relaxation phase of the heartbeat |
| systole | the contraction of the chambers of the heart (especially the ventricles) to drive blood into the aorta and pulmonary artery |
| lubb | closure of the tricuspid and mitral valves at the beginning of systole |
| dubb | closure of the aortic and pulmonary valves at the end of systole |
| murmur | abnormal heart sound caused by improper valve closure |
| Bruit | adventitious sound of venous or arterial origin on auscultation |
