Chp 6-Cardiovascular

aorta Largest artery of the body; vessel through which oxygenated blood exits the heart
Arteriole A tiny artery connecting to a capillary
Artery A thick-walled blood vessel that, in systemic circulation, carries oxygenated blood away from the heart
Atrioventricular bundle bundle of fibers in the interventricular septum that transfers charges in the hearts conduction system; also called the bundle of His
Atrium Either of the two upper chambers of the heart
blood essential fluid made up of plasma and other elements that circulates throughout the body; delivers nutrients to and removes waste from the body's cells
blood pressure measure of the force of blood surging against the walls of the arteries
bundle of His same as atrioventricular bundle
capillary the smallest blood vessel that forms the exchange point between the arterial and venous vessels
carbon dioxide waste material transported in the venous blood
carotid artery artery that transports oxygenated blood to the head and neck
diastole Relaxation phase of a heartbeat
Ductus arteriosus Structure in the fetal circulatory system through which blood flows to bypass the fetus's nonfunctioning lungs
endocardium membranous lining of the chambers and valves of the heart; the innermost layer of heart tissue
femoral artery an artery that supplies blood to the thigh
heart muscular organ that receives blood from the veins and sends it into the arteries
inferior vena cava large vein that draws blood from the lower part of the body to the right atrium
left atrium upper left heart chamber
left ventricle lower left heart chamber
myocardium muscular layer of heart tissue between the epicardium and the endocardium
popliteal artery an artery that supplies blood to the cells of the area behind the knee
pulmonary artery one of two arteries that carry blood that is low in oxygen from the heart to the lungs
Purkine fibers specialized fibers that conduct the charge
pulmonary vein one of four veins that bring oxygenated blood from the lungs to the left atrium
pulse rhythmic expansion and contraction of a blood vessel, usually an artery
right atrium upper right chamber of the heart
right ventricle lower right chamber of the heart
septum partition between the left and right chambers of the heart
sinus rhythm normal heart rhythm
superior vena cava large vein that transports blood collected from the upper part of the body to the heart
systole contraction phase of the heartbeat
ventricle either of the two lower chambers of the heart
angi(o) blood vessel
aort(o) aorta
arteri(o) artery
ather(o) fatty matter
atri(o) atrium
cardi(o) heart
phleb(o) vein
Ven(o) vein
aden(o) gland
ech(o) sound
hem(o) blood
electr(o) electric
AMI acute myocardial infarction
AV atrioventricular
BP blood pressure
CABG coronary artery bypass graft
CAD coronary artery disease
CHD coronary heart disease
CHF congestive heart failure
CPR cardiopulmonary resuscitation
CVA cerebrovascular accident
CVD cardiovascular disease
DSA digital subtraction angiography
DVT deep venous thrombosis
arteriography viewing of a specific artery by x-ray after injection of a contrast medium
auscultation process of listening to body sounds via a stethoscope
cholesterol fatty substance present in animal fats; cholesterol circulates in the bloodstream , sometimes causing arterial plaque to form
doppler ultrasound ultrasound test of blood flow in certain blood vessels
echocardiography use of sound waves to produce images showing the stucture and motion of the heart
holter monitor portable device that provides a 24 hour electrocardiogram
phlebography viewing of a vein by x-ray after injection of a contrast medium
sonography production of images based on the echoes of sound waves against structures
sphygmomanometer device for measuring blood pressure
stress test test that measures heart rate, blood pressure, and other body functions while the patient is exercising on a treadmill
aneurysm ballooning of the artery wall caused by weakness in the wall
angina pectoris chest pain, usually caused by a lowered oxygen or blood supply to the heart
aortic regurgitation backward flow or leakage of blood through a faulty aortic valve
arrhythmia irregularity in the rhythm of the heartbeat
asystole cardiac arrest
atheroma a fatty deposit (plaque) in the wall of an artery
bradycardia heart rate of fewer than 60 beats per minute
cardiac arrest sudden stopping of the heart; also called asystole
claudication limping caused by inadequate blood supply during activity; usually subsides during rest
congestive heart failure inability of the heart to pump enough blood out during the cardiac cycle; collection of fluid in the lungs results
coronary artery disease condition that reduces the flow of blood and nutrients through the arteries of the heart
cyanosis bluish or purplish coloration, as of the skin, caused by inadequate oxygenation of the blood.
deep vein thrombosis formation of a thrombus (clot) in a deep vein, such as a femoral vein
dysrhythmia abnormal heart rhythm
fibrillation random, chaotic, irregualr heart rhythm
flutter regular but very rapid heartbeat
gallop triple sound of a heartbeat, usually indicative of serious heart disease
hemorrhoids varicose condition of veins in the anal region
hypertension chronic condition with blood pressure greater than 140/90
hypotension chronic condition with blood pressure below normal
infarct area of necrosis caused by a sudden drop in the supply of arerial or venous blood
ischemia localized blood insufficiency caused by an obstruction
mitral stenosis abnormal narrowing at the opening of the mitral valve
murmur soft heart humming sound heard between normal beats
myocardial infarction sudden drop in the supply of blood to an area of the heart muscle, usually due to a blockage in a coronary artery
occlusion the closing of a blood vessel
perfusion deficit lack of flow through a blood vessel, usually caused by an occlusion
phlebitis inflammation of a vein
pulmonary edema abnormal accumulation of fluid in the lungs
rub frictional sound heard between heartbeats, usually indicating a percardial murmur
tachycardia heart rate greater than 100 beats per minute
thrombus stationary blood clot in the cardiovascular system, usually formed from matter found in the blood
varicose dilated, enlarged, or twisted wein, usually on the leg
angioplasty opening of a blocked blood vessel, as by balloon dilation
arteriotomy surgical incision into an artery, especially to remove a clot
balloon catheter dilation insertion of a balloon catheter into a blood vessel to open the passage so blood can flow freely
bypass a structure (usually a vein graft) that creates a new passage for blood to flow from one artery to another artery or port of an artery; used to create a detour around blockages in arteries
embolectomy surgical removal of an embolus
endarterectomy surgical removal of the diseased portion of teh lining of an artery
graft any tissue or organ implanted to replace or mend damaged areas
stent surgically implanted device used to hold something (as a blood vessel) open
thrombectomy surgical removal of a thrombus
venipuncture small puncture into a vein, usually to draw blood or inject a solution
antianginal agent used to relieve or prevent attacks of angina
antiarrhythmic agent used to help normalize cardiac rhythm
anticoagulant agent that prevents the formation of dangerous clots
antihypertensive agent that helps control high blood pressure
beta blocker agent that lowers blood pressure by reducing contraction strength of the heart muscle; slows heartbeat
diuretic medication that promotes the excretion fo urine
thrombolytic agent that dissolves a thrombus
vasoconstrictor agent that narrows the blood vessel
vasodilator agent that dilates or widens the blood vessels
