membrane lining the
cavities of the heart
epicardium
membrane forming the
puter layer of teh 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
ventricle
lower right or left chamber
of the heart
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 the left ventricle
pulmonary semilunar valve
heart valve opening from the right ventricle to the pulmonary artery
tricuspid valve
valve b/t the right atrium and the right ventricle
valves of teh veins
valves located at intervals within the lining of veins, especially in the legs which constrict wth muscle action to move the blood returning to the heart
arteries
vessels that carry blood from the heart to the arterioles
aorta
large artery that is teh 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
circulationj of the blood throughout the body through arteries, arterioles, cappillaries, venules, and veins to deliver oxygen and nutrients to body tissues
coronary circulation
circulation of blood through the coronary blood vessels to deliver oxygen and nutrients to the heart muscle
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
systemic circulation
circulationj of the blood throughout the body through arteries, arterioles, cappillaries, venules, and veins to deliver oxygen and nutrients to body tissues
diastole
to expand; period in the cardiac cycle
when blood enters the relaxed ventricles from the atria
systole
to contract; period in the cardiac cycle when the heart is in contraction and blood is ejected through the aorta nd pulmonary artery
normotension
normal blood pressure
hypotension
low blood pressure
hypertension
high blood pressure
arteriosclerosis
thickening, loss of elasticity and calcification(hardening) of arterial walls
atherosclerosis
buildup of fatty subsances 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 ( air, fat, foreign object) carried in the bloodstream that obstructs when it lodges

(embolus = a stopper)
stenosis
condition of narrowing of a part
constriction
compression of a part
occlusion
plugging, obstruction or a closing off
ischemia
to hold back blood; decreased blood flow to tissue caused by constriction or occlusion of a blood vessel
perfusion deficit
a lsck of flow through a blood vessel caused by a narrowing, occlusion, etc.
infarct
to stuff; a localized area of necrosis
caused by ischemia resulting from occlusion of a blood vessel.
angina pectoris
chest pain causd by a temporary loss f oxygenated blood to heart muscle often caused by narrowing of coronary arteries

(angina= to choke)
aneurysm
a widening; bulging of the wall of tbe heart, aorta, or artery caused by congenital defect or acquired weakness
saccular aneurysm
a saclike bulge on one side
fusiform aneurysm
a spindle shaped bulge
dissecting aneurysm
a split or tear of the vessel wall
claudication
to limp; pain in a limb ( especially rh calf) while walking that subsides after rest; caused by inadequate blood supply
heart murmur
an abnormal sound from the heart produced by defects in the chambers or valves
vegetation
to grow; an abnormal growth of tissue around a valve, generally a result of infection
sinatrial node
the pacemaker; highly specialized neurologic tissue impeded in the wall of the right atrium responsible for initiating electrical conduction of the heartbeat , causing the stria to contract and firing conduction of impulses to the AV node
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 the 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; resting state of a myocardial cell
depolarization
change of a mycardial cell from a polarized 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 teh SA node (avg. rate 60-100 bpm)
arhythmia
any of several kinds of irregularity or loss of rhythm of the heartbeat
