Cardiovascular
Med Term Cardiovascular System
| Question | Answer |
|---|---|
| card/o, cardi/o | heart |
| arteri/o | arteries |
| capill/o | capillaries |
| phleb/o, ven/o | veins |
| hemo/o, hemat/o | blood |
| heart | pumps blood into the arteries |
| arteries | transports blood to all body parts |
| capillaries | exchange nutrients and waste products with cells |
| veins | return blood to the heart |
| blood | brings oxygen and nutrients to all cells and carries away waste |
| pericardium | double walled memrane that encloses the heart |
| pericardial fluid | between the layers - prevents friction when the heart beats |
| epicardium | external layers of the heart. Also the internal layer of the pericardium |
| myocardium | middle and thickest of the three layers. Cardiac muscle |
| endocardium | lining of the heart. comes in direct contact with blood |
| atria | two upper heart chambers (receiving chambers) |
| ventricles | lower chambers |
| tricuspid valve | controls opening between right atrium and right ventricle |
| Mitral valve/ bicuspid valve | controls opening between left atrium and left ventricle |
| pulmonary semilunar valve | located between right ventricle and the pulmonary artery |
| aortic semilunar valve | located between the left ventricle and aorta |
| P wave | contractions of the atria |
| QRS wave | contraction of the ventricles |
| T wave | Relaxation of the ventricles |
| lubb sound | tricuspid and mitral valves closing |
| dupp sound | closing of the semilunar valves |
| atherosclerosis | hardening and narrowing of the arteries due to buildup of cholesterol plaques |
| ischemia | deficiency in blood supply due to either constriction or obstruction |
| myocardial infarction | heart attack - occlusion (closing) of a coronary artery |
| carditis | inflammation of the heart |
| endocarditis | inflammation of the endocardium |
| myocarditis | inflammation of the myocardium |
| pericarditis | inflammation of the pericardium |
| valvulitis | inflammation of the heart valves |
| mitral valve prolapse | abnormal protrustion of the mitral valve which results in incomplete closure |
| mitral stenosis | abnormal narrowing of mitral valve opening |
| cardiac flutter | arrhythmia in which the atrial contractions are rapid but regular |
| palpitations | pounding or racing of the heart with or without irregular rhythms |
| arteriosclerosis | hardening of the arteries |
| phlebitis | inflammation of the veins |
| thrombosis | blood clot |
| thrombus | blood clot is attached to the interior wall of blood vessel |
| embolus | bloot clot is ciruclating through the body |
| septicemia | presence of microorganisms in the blood - blood poisoning |
| anemia | lower than normal levels of RBC |
| angiography | visualization of vessels after injecting contrast medium |
| valvoplasty | surgical repair of heart valve |
| defibrillation | use of electrical shock to restore heart's normal rhythm |
| pacemaker | electronic device (internal or external) to monitor the hearts rhythm |
| Angina Pectoris | chest pain caused by partial occlusion of blood vessel |
| angiography | radiographic (recording) study of blood vessels |
| angiocardiography | radiographic study of the cardiac blood vessels |
| aplastic anemia | absence of all formed blood elements. Caused by failure of blood cell production in bone marrow |
| pernicious anemia | autoimmune disorder in which RBC are abnormally formed due to inability to absorb vitamin B12 |
| angionecrosis | death of walls of blood vessel |
| angiostenosis | narrowing of blood vessels |
| This disease is characterized by fluid build up | Congestive Heart Failure |
| This disease is caused from buildup of plaque on arterial walls | atherosclerosis |
| Myocardial Infarction | heart attack |
| This disease presents with severe chest pain, SOB and is caused from total occlusion of blood vessel | Myocardial Infarction |
| AB | universal recipient |
| O | universal donor |
