| Question | Answer |
| Aorta | Largest artery |
| Inferior Vena Cava | carries oxygen-poor blood to the right atrium from the lower half of the body |
| Left Atrium | the left upper chamber of the heart |
| Mitral valve | the valve between the left atrium and left ventricle |
| Left Ventricle | left lower chamber of the heart |
| Pulmonary Vein | carries oxygen-rich blood from the lungs to the left atrium of the heart |
| Pulmonary Valve | flaps between the right ventricle and the pulmonary artery |
| Pulmonary Artery | carries oxygen-poor blood from the right ventricle of the heart to the lungs |
| Right Atrium | the right upper chamber of the heart |
| Pericardium | loose fitting double layer sac |
| Endocardium | inner most layer of the heart |
| Myocardium | middle layer of the heart |
| Epicardium | outermost layer of the heart |
| Arteries | carries blood away from the heart |
| Veins | carries blood toward the heart |
| Arterioles | smallest branch of an artery |
| Capillaries | exchange nutrients and waste between blood and tissue fluid |
| Pulmonary Circulation | carries blood from the right ventricle to the lungs and to the left atrium |
| Systemic Circulation | carries blood to the rest of the body and then back to the heart |
| Coronary Artery Disease | caused by plaque build up and decreased blood and oxygen to the heart |
| Myocardial Infarction | heart attack |
| Bacterial Endocarditis | infection of the valves and endocardium |
| Rheumatic Heart Disease | damage to the heart muscle and heart valves caused by strep |
| Arrhythmia | any deviation from the normal pattern of the heartbeat |
| Heart (AV) Blocks | interference with the normal conduction of electric impulses that control activity of the heart muscle |
