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 |
