membrane forming the outer layer of the heart
interatrial septum
partition between right and left atrium
interventricular septum
partition between right and left ventricle
myocardium
heart muscle
pericardium
protective sac enclosing the heart composed of two layers with fluid between
heart valves
structures within the heart that open and close with the heartbeat to regulate the one-way flow of blood
aortic valve
heart valve between the left ventricle and the aorta
mitral or bicuspid valve
heart valve between the left atrium and left ventricle
pulmonary or semilunar valve
heart valve opening from the right ventricle to the pulmonary artery
tricuspid valve
valve between the right atrium and the right ventricle
arteries
vessels that carry blood from the heart to arterioles
aorta
large artery that is the main trunk of the arterial system branching from the left ventricle
arterioles
small vessels that receive blood from the arteries
capillaries
tiny vessels that join arterioles and venules
venules
small vessels that gather blood from the capillaries into the veins
veins
vessels that carry blood to the heart from the venules
systemic circulation
circulation of blood throughout the body through arteries/veins (etc)to deliver oxygen/nutrients to body tissues
coronary circulation
circulation of blood through the coronary blood vessels to deliver oxygen and nutrients to the heart muscle tissue
pulmonary circulation
circulation of blood to and from the lungs through the pulmonary vein/artery, providing the exchange of gas
diastole
to expand
systole
to contract
normotension
normal blood pressure
hypotension
low blood pressure
hypertension
high blood pressure
arteriosclerosis
thickening, loss of elasticity, and calcification of arterial walls
atherosclerosis
buildup of fatty substances that harden within the walls of arteries
atheromatous plaque
a swollen area within the lining of an artery caused by the buildup of fat
thrombus
a stationary blood clot
embolus
a clot carried in the bloodstream that obstructs when it lodges
stenosis
condition of narrowing of a part
constriction
compression of a part
occlusion
plugging; obstruction or closing off
ischemia
to hold back blood; decrease blood flow by constriction or occlusion of a blood vessel
perfusion deficit
the lack of flow through a blood vessel
infarct
to stuff; a localized area of necrosis caused by ischemia resulting from occlusion of a blood vessel
angina pectoris
chest pain caused by a temporary loss of oxygenated blood to heart muscle
aneurysm
a widening; bulging of the wall of the heart, aorta, or artery
claudication
to limp; pain in a limp while walking that subsides after rest
heart murmur
an abnormal sound from the heard produced by defects in the chambers or valves
palpitation
subjective experience of pounding, skipping, or racing heartbeats
vegetation
to grow; an abnormal growth of tissue around a valve, generally a result of infection
sinoatrial node
a pacemaker
atrioventricular node
neurologic tissue in the center of the heart that receives and amplifies the conduction of impulses from the SA node to the bundle of His
bundle of His
neurologic 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
Purkinje fibers
fibers in the ventricles that transmit impulses to the right and left ventricles, causing them to contract
polarization
resting
depolarization
change of a myocardial cell from a polarized state to a state of contraction
arrythmia
any of several kinds of irregularity or loss of rhythm of the heartbeat
bradycardia
slow heart rate
fibrillation
chaotic, irregular contractions of the heart
flutter
extremely rapid but regular contractions of the heart
premature ventricular contraction
a ventricular contraction preceding the normal impulse initiated by the SA node
tachycardia
fast heart rate
arteriosclerotic heart disease
a degenerative condition of the arteries characterized by thickening of the inner lining, loss of elasticity, and susceptibility to rupture
bacterial endocarditis
a bacterial inflammation that affects the endocardium or the heart valve
cardiac tamponade
compression of the heart produced by the accumulation of fluid in the pericardial sac
cardiomyopathy
a general term for disease of the heart muscle
congenital anomaly of the heart
malformations of the heart present at birth
cor pulmonale
enlargement of the right ventricle resulting from chronic disease within the lungs that causes congestion within the pulmonary circulation and resistance of blood flow to the lungs
congestive heart failure
failure of the left ventricle to pump an adequate amount of blood to meed the demands of the body resulting in a bottleneck of congestion in the lungs
coronary artery disease
a condition affecting arteries of the heart that reduces the flow of blood and delivery of oxygen and nutrients to the myocardium
hypertension
persistently high blood pressure
mitral valve prolapse
protrusion of one or both cusps of the mitral valve back into the left atrium during ventricular contraction
myocardial infarction
heart attack
myocarditis
inflammation of the myocardium most often cause by viral or bacterial infection
pericarditis
inflammation of the pericardium
phlebitis
inflammation of a vein
rheumatic heart disease
damage to heart muscle and heart valves by rheumatic fever

formation of a clot in a deep vein of the body
angiogram
record obtained by angiography
sonography
sonographic imaging
anastomosis
opening
defibrillation
termination of ventricular fibrillation by delivering an electrical stimulus to the heart
diuretic
a drug that increases the secretion of urine
