atrium

heart

circle or crown

muscle

chest

pulse

clot

vein

swollen, twisted vein

ventricle (belly or pouch)

upper right and left chambers of the heart

membrane lining the inner cavities of the heart

membrane forming the outer layer of the heart

partition between right and left atrium

partition between right and left ventricle

heart muscle

protective sac enclosing the heart composed of two layers with fluid between

outer layer (parietal = pertaining to wall) partition

fluid-filled cavity between the pericardial layers

layer closest to the heart (visceral = pertaining to organ)

lower right and left chanbers of the heart

structures within the heart that open and close with the heartbeat to regulate the one-way flow of blood

heart valve between the left ventricle and the aorta

heart valve between the left atrium and the left ventricle (cupis = point)

heart valve opening from the right ventricle to the pulmonary artery

valve between the right atrium and the right ventricle

valves located at intervals within the lining of veins, especially in the legs, which constrict with muscle action to move the blood returning to the heart

vessels that carry blood FROM the heart to the arterioles

large artery that is the main trunk of the arterial system branching from the left ventricle.

small vessels that reveive blood from the arteries

tiny vessels that join arterioles and venules

small vessels that gather blood from capillaries into the veins

vessels that carry blood to the heart from the venules

circulation of blood throughout the body through arteries, arterioles, capillaries and veins to deliver oxygen and nutrients to body tissues

circulation of blood through the coronary blood vessels to deliver oxygen and nutrients to the heart muscle tissue

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.

to expand; perio in the cardiac cycle when blood enters the relaxed ventricles from the artria

to contract; period in the cardiac cycle when the heart is in contraction and blood is ejected through the aorta and pulmonary artery

normal blood pressure

low blood pressure

persistently high blood pressure

the pacemaker

 the amplifier to the pacemaker

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

regular rhythm of the heart cycle stimulated by the SA node

thickening, loss of elasticity and calcification (hardening) of the arterial walls

buildup of fatty substances within the walls of arteries

a swollen area within the lining of an artery caused by the buildup of fat (lipids)

a stationary blood clot

a clot carries in the bloodstream that obstructs when it lodges (embolus = a stopper)

a condition of narrowing of a part

compression of a part

plugging; obstruction or a closing off

 to hold back blood; decreased blood flow to tissue caused by the constriction or occlusion of a blood vessel

a lack of flow through a blood vessel caused by narrowing, occlusion, etc.

to stuff; a localized area of necrosis caused by ischemia as a result of occlusion of a blood vessel

chest pain caused by a temporary loss of oxygenated blood to heart muscle often caused by narrowing of the coronary arteries

to choke

a widening; bulging of the wall of the heart, the aorta, or an artery caused by congenital defect or acquired weakness.

to limp; pain in a limb (especiallt the calf) while walking that subsides after rest; it is caused by inadequate blood supply

profuse sweating

an abnormal sound from the heart produced by defects in the chambers or valves

subjective experience of pounding, skipping or racing heartbeats

to grow; an abnormal growth of tissue around a valve, generally a result of an infection such as bacterial endocarditis

any of several kinds of irregularity or loss of rhythm of the heartbeat

slow heartbeat (< 60 bpm)

fast heart rate (>100 bpm)

a degenerative condition of the arteries characterized by thickening of the inner lining, loss of elasticity and susceptibility to rupture - seem most often in the aged or smokers

a bacterial inflammation that affects the endocardium or the heart valves

compression of the heart produced by the accumulation of fluid in the pericardial sac as results from pericarditis or trauma, causing rusture of a blood vessel within the heart

a general term for disease of the heart muscle

malformations of the heart present at birth

irregularity

an anomaly that consists of four defects: pulmonary stenosis, ventricular septal defect, malposition of the aorta and right ventricular hypertrophy - causes blood to bypass the pulmonary circulation so that deoxygenated blood goes into the systemic circulation, resulting in cyanosis

an opening in the septum separating the ventricles

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 that may extend to the veins, cauing edema in lower portions of the body

a condition affecting arteries of the heart that reduces the flow of blood and delivery of oxygen and nutrients to the myocardium - most often caused by atherosclerosis

high blood pressure NOS

high blood pressure caused by the effects of another disease

protrusion or one or both cusps of the mitral valve back into the left atrium during ventricular contraction, resulting in incomplete closure and backflow of blood

heart attack; necrosis of myocardial tissue (infarction) owing to loss of blood flow (ischemia) as a result of an occlusion of a coronary artery.

inflammation of the myocardium most often cause by viral or bacterial infection

inflammation of the pericardium

inflammation of a vein

damage to heart muscle and heart valves by rheumatic fever (a streptococcal infection)

inflammation of a vein associated with a clot formation

abnormally swollen, twisted veins with defective valves, most often seen in the legs

formation of a clot in a deep vein of the body - occurring most often in the femoral and iliac veins

a physical examination method of listening to sounds within the body with the aid of a stethoscope

noise; an abnormal heart sound caused by turbulence within - can also be in a vessel ex. the noise heart in an implanted vein used for dialysis

an electrical picture of the hear trepresented by positive and negative deflections on a graph labeled with the letters P, Q, R, S, and T corresponding to events of the cardiac cycle.

use of nuclear isotopes and computed tomography techniques to produce profusion (blood flow) images and study the cellular metabolism of the heart; can be taken at rest of with stress.

xray imaging

an xray of a blood vessel after injection of contrast medium

a record obtained by angiography
