ather/o
fatty (lipid) paste
coron/o
circle or crown
pector/o, steth/o
chest
sphygm/o
pulse
varic/o
swollen, twisted vein
atrium
upper right or left chamber of the heart
interatrial septum
partition between the right and left atria
visceral pericardium
layer closest to the heart (visceral= pertaining to organ)
parietal pericardium
outer layer (parietal= pertaining to the wall)
pericardial cavity
fluid-filled cavity between the pericardium layers
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 valve, bicuspid valve
heart valve between the left atrium and left ventricle (cuspis= point)
pulmonary semilunar valve
heart valve opening from the right ventricle to the pulmonary artery (luna= moon)
tricuspid valve
valve between the right atrium and the right ventricle
arteries
vessels that carry blood from the heart to the 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 via arteries, arterioles, capillaries, venules, and veins to deliver O2 and nutrients to body tissues
coronary circulation
circulation of blood through the coronary blood vessels to deliver O2 and nutrients to the heart muscle tissue
pulmonary circulation
circulation of blood from the pulmonary artery through the vessels in the lungs and back to the heart via the pulmonary vein, providing for the exchange of gases
diastole
to expand; period during the cardiac cycle when blood enters the relaxed ventricles from the atria
systole
to contract; period during the cardiac cycle when the heart is in contraction and blood is ejected through the aorta and the pulmonary artery
normotension
normal blood pressure
sinoatrial (SA) node
the pacemaker; highy specialized, neurological tissue impeded in the wall of the right atrium; responsible for initiating electrical conduction of the heartbeat, cuasing the atria to contract and firing conduction of impulses to the AV node
atrioventricular (AV) node
neurological 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
neurological 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, Purkinje network
fibers in the ventricles that transmit impulses to the right and left ventricles, causing them to contract
polarization
resting; resting state of a myocardial cell
depolarization
change of a myocardial cell from a polarized (resting) state to a state of contraction
repolarization
recharging of the myocardial cell from a contracted state back to a resting state
normal sinus rhythm (NSR)
regular rhythm of the heart cycle stimulated by the SA node
aneurysm
a widening; a bulging of the wall of the heart, aorta, or artery caused by a congenital defect or acquired weakness
saccular aneurysm
sac-like bulge on one side
fusiform aneurysm
spindle-shaped bulge
dissecting aneurysm
split or tear of the vessel wall
angina pectoris
chest pain caused by a temporary loss of oxygenated blood to heart muscle; often caused by narrowing of the coronary arteries
arteriosclerosis
thickening, loss of elasticity, and calcification of arterial walls
atherosclerosis
form of arteriosclerosis characterized by the buildup of fatty substances that harden within the walls of arteries
artheromatous plaque
swollen area within the lining of an artery caused by the buildup of fat
claudication
to limp; pain in a limb while walking that subsides after rest; caused by inadequate blood supply
constriction
compression of a part that causes narrowing
diaphoresis
profuse sweating (perspiration)
embolus
a clot (air, fat, or foreign substance) carried in the bloodstream that obstructs the flow of blood when it lodges
heart murmur
abnormal sound from the heart produced by defects in the chambers or valves
infarct
to stuff; a localized area of necrosis
ischemia
to hold back blood; decreased blood flow to tissue caused by constriction or occlusion of a blood vessel
occlusion
plugging; an obstruction or a closing off
palpitation
subjective experience of pounding, skipping, or racing heartbeats
stenosis
condition of narrowing of a part
thrombus
blood clot
vegetation
to grow; abnormal growth of tissue around a valve (result of infection)
