| Circulation | the action of transporting blood to and from the body tissues |
| Heart | lies mostly to the left of the sternum and between the lungs |

| Myocardium | the middle layer of the muscles of the heart and thickest |
| Epicardium | the outer layer of the muscles of the heart |
| Pericardium | a sac of tissue that surrounds the heart |
| Parietal layer | the outside layer of the pericardium that is hard and tough |
| Visceral layer | the inside layer of the pericardium that is right next to the epicardium |
| Right atrium | receives the blood from the body |
| Left atrium | receives the blood from the lungs |
| Right ventricle | receives the blood that is deoxygenated from the body |
| Left ventricle | receives the blood that is oxgenated from the lungs |
| Tricuspid valve | valve between the right atrium and right ventricel |
| Bicuspid valve | valve between the left atrium and the left ventricle |
| Papillary muscles | muscles in the ventricles that anchor the chordae tendineas and atrioventricular valves |
| Mitral valve | another name for the bicuspid valve |
| Pulmonary artery | large artery that transports deoxygenated blood from the right ventricle to the lungs |
| Aorta | largest artery in the body, that transports oxygenated blood from the left ventricle to the body |
| Pulmonary semilunar valve | between the right ventricle and pulmonary artery |
| Aortic semilunar valve | between the left ventricle and aorta |
| Pulmonary veins | transport oxygenated blood back into the left atrium |
| Deoxygenated blood | blood that does not contain oxygen |
| Oxygenated blood | blood that has oxygen |
| Vena cava | largest vein in the body that provides a pathway for deoxygenated blood to the heart |
| Diastole | the phase of the cardiac cycle when the heart is relaxing and expanding and filling with blood |
| Systole | the contraction phase of the cardiac cycle when the heart is pumping blood out to lungs and body |

| myocardial infarction | heart attach |
| Holter monitor | a device worn by a patient that records prolonged electrocardiograph readings on a portable tape recorder |
| angioplasty | surgery that opens a blocked artery by inflating a small balloon within a catheter to widen and restore blood flow in the artery |
| cardioversion | restoration of normal heart rhythm by applying an electrical counter shock to the chest using a device (defibrillator); also called defibrillation |
