| myocardium | cardiac muscle tissue in walls of heart chambers |
| apex | lower portion of heart |
| ventricles | lower heart chambers |
| atria | upper heart chambers |
| receive blood | what atria do |
| septum | divides heart into two sides |
| pump blood out of heart | what ventricles do |
| endocardium | membrane which lines heart chambers |
| endocarditis | inflammed endocardium |
| pericardium | heart covering |
| parietal pericardium | outer layer of heart covering |
| visceral pericardium | inner part of pericardium |
| pericarditis | inflammed pericardium |
| pericardial edema | fluid collects between pericardial layers |
| pericardial effusion | fluid collection between pericardial layers impairs pumping action |
| cardiac tamponade | heart compression |
| systole | heart contracts |
| diastole | heart relaxes |
| mitral valve | between left atrium and left ventricle |
| tricuspid valve | between right atrium and right ventricle |
| semilunar valves | between arteries that lead from the heart and ventricles |
| incompetent valves | valves that leak |
| stenosed valves | valves that are too narrow |
| mitral valve prolapse | valve flaps extend back into atrium causing some leakage |
| heart murmurs | caused by valve disorders |
| right atrium | Blood goes from vena cava to here |
| right ventricle | chamber that blood enters after right atrium |
| pulmonary artery | where blood goes from right ventricle |
| lungs | pulmonary vein goes here |
| becomes oxygenated | happens to blood in lungs |
| pulmonary vein | goes from lungs to left atrium |
| left ventricle | heart chamber where blood goes after left atrium |
| aorta | blood vessel leading out of left ventricle |
| pulmonary circulation | movement of blood from right ventricle to lungs and back to heart |
| systemic circulation | movement of blood from left ventricle throughout the body. |
| rheumatic fever | heart damage due to strep infection |
| coronary circulation | blood delivery to and from heart |
| coronary arteries | deliver blood to heart |
| angina pectoris | chest pain due to inadequate oxygen delivery to heart |
| atherosclerosis | arterial blockage due to lipid buildup |
| myocardial infarction | heart tissue damage due to oxygen deprivation |
| coronary bypass | surgery done to alleviate clogged arteries |
