| partition between the right and left atria | interatrial septum |
| partition between the right and left ventricles | interventricular septum |
| myocardium | heart muscle |
| protective sac enclosing the heart composed of two layers with fluid between. | pericardium |
| lower right and left chambers of the heart. | ventricle |
| structures within the heart that opens and closes with the heartbeat to regulate one-way flow of blood. | heart valves |
| heart valve between the left ventricle and the aorta | aortic valve |
| heart valve between the left atrium and the left ventricle. | mitral valve |
| heart valve openingfrom the right ventricle to the pulmonary artery. | pulmonary semilunar valve |
| valve between the right atrium and the right ventricle | tricuspid valve |
| large artery that is the main trunk of the arterial system branching frim the left ventricle. | aorta |
| small vessels that receive blood from arteries | arterioles |
| tiny vessels that join arteries and venules | capillaries |
| small vessels that gather blood from the capillaries into the veins. | venules |
| vessels that carry blood to the heart from the venules. | veins |
| to expand; period during the cardiac cycle when blood enters the relaxed ventricles from the atria | diastole |
| to contract; period during the cardiac cycle when the heart is in contraction blood is ejected through the aorta and the pulmonary artery | systole |
| high blood pressure. | hypertension |
| fibers in the ventricles that transmit impulses to the right and left ventricles, causing them to contract. | Purkinje fibers |
| change of a myocardial cell from a polarized state to a state of contraction | depolarization |
| recharging the myocardial cell from a contractedstate back to a resting state. | repolarization |
| regular rythm of the heart cycle stimulated by the SA node | normal sinus rythm |
| widening, a bulging of the wall of the heart, aorta, or artery caused by a congenital defect or acquired weakness | aneurysm |
| chest pain caused by a temporary loss of oxygenated blood to heart muscle, often caused by narrowing of the coronary arteries. | angina pectoris |
| characterized by the buildup of fatty substances that harden within the walls of arteries. | arteriosclerosis |
| profuse sweating | diaphoresis |
| a clot carried in the bloodstream that obstructs the flow of blood when it lodges | embolus |
| an abnormal sound from the heart produced by defects in the chambers of the valves | heart murmur |
| to stuff; a localized area of necrosis caused by ischemia resulting fro occlusion of a blood vessel | infarct |
| to hold back blood; decreased blood flow to tissue caused by constriction or occlusion of a blood vessel. | ischemia |
| any of several kinds of irregularity or loss of rythm of the heartbeat | arrythmia |
| slow heart rate | bradycardia |
| fast heart rate | tachycardia |
| a condition affecting arteries of the heart rate that reduces the flow of blood and the delivery of oxygen and nuutrients to the myocardium, most often caused by atherosclerosis | coronary artery disease (CAD) |
| persistently high blood pressure | hypertension |
| high blood pressure attributed to no single cause; risks include soking, obesity, increased salt intake, hypercholosterolemia, and heriditary factors. | essential hypertension |
| the abrupt cessation of any cardiac output , most commonly the result of ventricular fibrillation;causes sudden death unless defibrillation is initiated immediately | sudden cardiac arrest |
| formation of a clot in a deep vein of the body, occuring most often in the femoral and iliac veins | deep vein thrombosis |
| inflammation of a vein | phlebitis |
| abnormally swollen, twisted veins with defective valves, most often seen in the legs. | varicose veins |
| physical examination method of listening to soundswithin th ebody with a stethescope | auscultation |
| represented by positive and negative deflections on a grpah labled withe the an electrical picture of the heart | electrocardiogram |
| measurement of the amount of blood ejected from a ventricle in one contraction | stroke volume |
| grafting a portion of a blood vessel retrieved from another part of the body | coronary artery bypass graft (CABG) |
| opening; the joining of two blood vessels to allow flow from one to the other. | anastomosis |
| a device used to treaat slow heart rates ny electrically stimulating the heart to contract; most often, it is implanted with lead wires and battery circuitry under the skin. | pacemaker |
| drug that dialates coronary arteries restoring oxygen to the tissuues to relieve the pain of angina pectoris. | antianginal |
| drug that increases the secretion of urine; commonly prescribed in treating hypertension. | cardiotonic |
| blood pressure | BP |
| coronary artery bypass graft | CABG |
| deep vein thrombosis | DVT |
| electrocardiogram | ECG or EKG |
| hypertension | HTN |
| myocardial infarction | MI |
| sudden cardiac arrest | SCA |
| the pacemaker; highly specialized, neurological tissue impeded in the wall of the right atrium; responsible for initiating electrical conduction of the heartbeat, causing the atria to contract and firing conduction of impulses to the AV node | sinoatrial (SA) node |
| neurological tissue in the center of the heart that receives and amplifies the conduction of the impulses from the SA node to the bundle of His | atrioventricular (AV) node |
| neurological fibers extending from the AV node to the right and left bundle branches that fire the impulse from the AV node to the Purkinje fibers | bundle of His |
| heart attack; deat of myocardial tissuecaused by ischemia as a result of an occlusion of a coronary artery; usually caused by atherosclerosis; symptoms include pain in thechest or upper body,shortness of breath, diaphoresis, and nausea. | myocardial infarction |
