| epicardium | outer layer of the heart |
| myocardium | middle, thick, muscular layer of the heart |
| endocardium | inner layer of the heart |
| sinoatrial node (SA node) | the pacemaker where the electrical impulse of the hear originates |
| atrioventricular node (AV node) | located between the right atrium and right ventricle |
| Bundle of His | transmission of electrical impulses to both ventricles of the heart |
| circulation | movement of blood through vessels throughout the body |
| pulmonary circulation | circulation between the heart and the lungs |
| systemic circulation | circulation of blood between the heart and the rest of the body |
| superior vena cava | one of the two largest veins of the body |
| inferior vena cava | one of the largest veins in the body |
| tricuspid valve | valve located between the right atrium and right ventricle |
| chordae tendinae | strong fibrous bands that attach the corners of the heart valves to the muscles of the lower heart chambers |
| papillary muscles | are attached to the undersurfaces of the valve cusps, also contract pulling open the valve |
| pulmonary valve | a valve consisting of three semilunar cusps separating the pulmonary trunk from the right ventricle |
| pulmonary artery | transports deoxygenated blood from the right ventricle to the lungs |
| oxygenation | process by which waste filled blood is exchanged for oxygen rich blood in the lungs |
| pulmonary vein | vessel that returns oxygenated blood to the heart |
| bicuspid valve | valve between the left ventricle; also know as the mitral valve |
| aortic valve | valve between the left ventricle and the aorta |
| aorta | largest artery on the body |
| arteries | carry oxygen-rich blood away from the heart to various parts of the body |
| arterioles | small vessels branching off from ateries |
| capillaries | small vessels branching off from arterioles |
| sphygmomanometer | instrument used to measure blood pressure |
| stethoscope | an instrument used to hear and amplify the sounds made by the heart, lungs, and other internal organs |
| systole (systolic blood pressure) | pressure in the vessels as the heart is contracting |
| diastole (diastolic pressure) | the pressure in the vessels when the heart is at rest, between contractions |
| cardiology | the branch of medicine that studies the function and disorders of the heart |
| cardiologist | a physician who specializes in diseases and disorders of the cardiovascular system |
| electrocardiogram (EKG, ECG) | graphic record of the electrical activity of the heart |
| angina pectoris | chest pain related to stress, exercise, extreme cold; constriction of blood vessels |

| arteriosclerosis | hardening of the arteries |
| arteriosclerotic heart disease | heart disease caused by hardening of arteries |
| atherosclerosis | narrowing/hardening of arteries as fat deposits on walls of vessels |
| cardiac arrest | sudden stoppage of the heart |
| cardiac catherization | procedure where a catheter is guided through a vein or artery into the hear and x-ray pictures are taken |
| cardiopulmonary resuscitation (CPR) | life saving procedure used after heart stoppage, involves artificial respiration and manual external compression of the heart |
| congestive heart failure | disease process in which the heart cannot pump enough blood to meet the needs of the tissues |

| coronary artery disease (CAD) | abnormal condition which can affect the arteries of the heart |
| echocardiogram | procedure using sound waves to visualize the heart |
| hypertension | high blood pressure |
| myocardial infarction (MI) | heart attack; insufficient blood supply to heart muscle causes death to the affected area |
| vasocontriction | narrowing of a vessel due to constriction |
| bradycardia | slow heart rate |
| bundle branch block (BBB) | electrical impulse to either right or left bundle branch is interrupted |
| fibrillation | atria or ventricles rapidly and incompletely contract due to chaotic electrical activity |
| palpitation | fluttering/abnormal throbbing of heart |
| paroxysmal atrial tachycardia (PAT) | begins and ends suddenly, where there is a rapid atrial contraction |
| premature atrial contraction (PVC) | ventricles contract too early |
| premature atrial contraction (PAC) | atria contracts too early, before anticipated time |
| tachycardia | rapid heart rate/above 100 per minute |
