Cardiovascular System

sac formed by localized dilation of an artery or vein

chest pain caused by decreased oxygen supply to heart

supplies oxygen-rich blood from heart to rest of body

between left ventricle and aorta

variation from normal rhythm of heartbeat

thickening and loss of elasticity of arterial walls, slowing blood flow

no heartbeat

form of ateriosclerosis in which fats are deposited on arterial walls

located in right atrium, responsible for coordinating contractions through ventricles

upper chambers of heart

slow heartbeat, pulse of less than 60

heart function stops

weakening of heart muscle

inflammation of heart muscle

sudden and acute vascular lesion of brain caused by hemorrhage, embolism, thrombosis, or rupturing blood vessels

cramplike pains in calves due to poor circulation

stricture or narrowing of vessel

flap on valves of heart

resting heartbeat

abnormal rythym

blocking of artery by embolus

foreign object carried by blood and forced into smaller vessel, causing blockage in circulation

inner surface of heart chambers

out layer of heart

small, local, involuntary muscular contraction caused by spontaneous activation of single muscle cells or muscle fibers

defective blood pumping system, marked by breathlessness and abnormal retention of sodium and water

persistent high blood pressure

localized area of ischemic necrosis causing blockage in blood supply

brings venous blood from lower regions of body to right side of heart

deficiency of blood flow to part of body

cavity or channel within any organ, space within artery, vein, intestine, etc

general vague body weakness/discomfort

space in chest between lungs where heart is

located between left atrium and ventricle, two leaflets

extra clicking sound, failure of heart valves to close properly

death of heart muscle due to absence of blood supply

middle, thickest layer of heart wall, made of cardiac muscle

closed

person must sit up or stand to breathe comfortably

special muscles connected to leaflets of valves to allow them to only open in one direction

exterior layer covering heart

cutting into a vein

deposit of fatty material in artery (atherosclerosis)

carries blood to lungs from right side of heart to get oxygenated

between pulmonary artery and right ventricle

carries oxygenated blood from lungs to left side of heart

longest veins located in lower extremities

heart's pacemaker located in right atrium responsible for coordinating heart contractions through atria

normal heartbeat originating from SA node

narrowing

brings venous blood from head and upper limbs to right side of heart

pumping/contracting phase of heartbeat

abnormally fast heart rate

inflammation of vein due to thrombus formation

blood clot

brief interruption of circulation to a portion of the brain. Precursor to stroke

located between right atrium and right ventricle, three leaflets

lower chambers of the heart

surgical removal of aneurysm

x-ray study of blood vessels

surgical or percutaneous reconstruction of blood vessels

removes or prevents blood clots

long, fine catheter is navigated through a peripheral blood vessel into chambers of heart using x-ray visualization as a guide

volume of blood (L) that heart pumps per minute

surgical incision or opening of heart for repair

brief charges of electricity applied to chest to stop cardiac arrythmia

circulation by secondary channels after obstruction of principal channel supplying heart

use of leg vein or synthetic material to substitute for a blocked artery in heart

promotes removal of excess interstitial fluid and results in increase urine

graphic recording of reflected ultrasound waves from heart

electrical recordings of heart activity by electrodes on chest wall

removal of interior portion of an artery and occluding fatty deposit

circulation of blood outside of body for purposes of removing or exchanging substances

dilation of blood vessel by balloon catheter inserted through skin into lumen of vessel to site of lesion; balloon inflated to flatten plaque against artery wall

device placed in artery after angioplasty surgery to keep from narrowing again

volume of blood pumped per contraction

use of radioactive tracer given during exercise to detect decreased blood flow to portion of heart

removal of blood clot

agent that dilates blood vessels

agent that constricts blood vessels
