| question/term | answer/definition |
| cardiovascular system | consists of the heart and blood vessels that work together to transport blood throughout the body |
| the heart ______ blood throughout the body | pumps |
| blood vessels ________blood throughout the body | transport |
| heart | muscular organ that consists of 4 chambers |
| 4 chambers of the heart | right atrium and left atrium (upper chambers) right ventricle and left ventricle (lower chambers ) |
| septum | divides the heart into left and right portions |
| interatrial septum | separates the atria |
| interventricular septum | separates the ventricles |
| heart valves open and close to maintain ________ through the heart | one way flow of blood |
| 4 heart valves | mitral, tricuspid, aortic, pulmonary |
| layers of the heart | endocardium, myocardium, epicardium, and pericardium |
| endocardium | membrane that lines the interior cavities of the heart |
| myocardium | thick, muscular layer |
| epicardium | outer membrane |
| pericardium | loose, protective sac that surrounds and encloses the heart |
| inferior and superior vena cava dump deoxygenated blood into the _________ | right atrium |
| atrial contraction leads to _______ | the opening of the tricuspid valve to allow blood to flow into the right ventricle |
| ventricular contraction leads to ______ | blood through the pulmonary valve into the pulmonary artery |
| pulmonary circulation | passage of blood from right ventricle through the pulmonary artery to lungs and back through the pulmonary veins to the left atrium |
| with atrial contraction the mitral valve opens to _______ | allow blood to flow into the left ventricle |
| systemic circulation | contraction of the left ventricle pushes blood through aortic valve into aorta and on to all parts of the body through arteries, arterioles, capillaries, venules, and veins |
| blood returns to the _______ | right atrium |
| coronary circulation | supplies blood to the heart |
| which organ is the first to receive oxygenated blood via right and left coronary arteries | heart |
| angi/o, vas/o, vascul/o | vessel |
| aort/o | aorta |
| arteri/o | artery |
| ather/o | fatty (lipid) paste |
| atri/o | atrium |
| cardi/o | heart |
| coron/o | circle or crown |
| my/o | muscle |
| pector/o, steth/o | chest |
| phleb/o, ven/o | vein |
| sphygm/o | pulse |
| thromb/o | clot |
| varic/o | swollen, twisted vein |
| ventricul/o | ventricle (belly or pouch) |
| blood pressure | force exerted by circulating blood on the walls of the arteries, veins, and heart chambers |
| blood pressure is determined by | the volume of the blood, the space within the arteries and arterioles, and the force of the heart contractions |
| diastole | period in cardiac cycle when blood enters relaxed ventricles from the atria |
| systole | period in cardiac cycle when heart is in contraction and blood is ejected through the aorta and pulmonary artery |
| normotension | normal blood pressure |
| hypotension | low blood pressure |
| hypertension | high blood pressure |
| cardiac conduction | provides electrical stimulus that is necessary to cause the heart muscle to pump blood by the continual contraction and relaxation of myocardial cells |
| myocardial= | heart muscle |
| cardiac conduction pattern | SA node -> AV node -> bundle of His -> right and left bundle branches -> purkinje fibers |
| pacemaker of the heart | sinoatrial node |
| states of myocardial cells during cardiac conduction | polarization -> depolarization -> repolarization |
| polarization | resting state |
| depolarization | contracting state |
| repolarization | resting state |
| ACE | angiotensin converting enzyme |
| ACS | acute coronary syndrome |
| ASD | atrial septal defect |
| CABG | coronary artery bypass graft |
| CAD | coronary artery disease |
| CCU | coronary care unit or critical care unit |
| CXR | chest x ray |
| EPS | electrophysiologic study |
| ECHO | echocardiography |
| MVP | mitral valve prolapse |
| NSR | normal sinus rhythm |
| PCI | percutaneous coronary intervention |
| PDA | patent ductus ateriosus |
| PVC | premature ventricular contraction |
| SCA | sudden cardiac arrest |
