TermDefinition
upper chamber of the heart that receives and holds blood that is about to enter the ventricle Atrium
Largest artery in the body Aorta
Blood vessels that carry blood away from the heart Arteries
Lower chamber of the heart that pumps blood out of the heart to the rest of the body Ventricle
Blood vessels that carry blood back to the heart Veins
Smallest blood vessels Capillaries
Blood pressure in the arteries during contraction of the ventricles. systolic pressure
occurs when the ventricles are relaxed; the lowest pressure against the walls of an artery diastolic pressure
the pacemaker of the heart sinoatrial node (SA node)
instrument to measure blood pressure sphygmomanometer
includes the flow of blood to all parts of the body except the lungs systemic circulation
a small artery arteriole
record of the electricity flowing through the heart electrocardiogram
small pinpoint hemorrhage petechiae
double-layered membrane surrounding the heart pericardium
inner lining of the heart endocardium
muscular, middle layer of the heart myocardium
listening with a stethoscope auscultation
a small vein venule
vessel angi/o
visualize the inside of a vessel/repair of a vessel angiogram/angioplasty
artery arteri/o
surgical procedure to remove the atheromatous plaque material, or blockage, in the lining of an artery constricted by the buildup of deposits endarterectomy
degeneration of the walls of the arteries caused by accumulated fatty deposits and scar tissue, and leading to restriction of the circulation and a risk of thrombosis atheroma
minimally invasive endovascular surgery technique for removing atherosclerosis from blood vessels within the body atherectomy
atrium atri/o
pertaining to the atria, the upper chambers of the heart atrial
arm brachi/o
major blood vessel of the (upper) arm brachial artery

high amounts of cholesterol in the blood hypercholesterolemia
blue cyan/o
a bluish discoloration of the skin resulting from poor circulation or inadequate oxygenation of the blood cyanosis
oxygen ox/o
deficiency in the amount of oxygen reaching the tissues hypoxia
pericardium pericardi/o
procedure where fluid is aspirated from the pericardium pericardiocentesis
vein phleb/o
process of making an incision in a vein with a needle. The procedure itself is known as a venipuncture phlebotomy
pulse sphygm/o
a medical instrument for listening to the action of someone's heart or breathing stethoscope
clot thromb/o
local coagulation or clotting of the blood in a part of the circulatory system thrombosis
valve valvul/o
balloon aortic valvotomy is the widening of a stenotic aortic valve using a balloon catheter inside the valve valvuloplasty
vessel vas/o
the constriction of blood vessels, which increases blood pressure vasoconstriction
the dilatation of blood vessels, which decreases blood pressure vasodilation
abnormal rapid heart rhythm fibrillation
rapid but regular contractions, usually of the atria flutter
congenital malformation involving four (tetra-) distinct heart defects tetralogy of fallot

measure -meter
hardening -sclerosis
tightening; structure -stenosis
no; not; without a-, an
slow brady-
fast tachy-
A condition resulting from the heart's inability to pump out all the blood that returns to it; blood backs up in the veins leading to the heart, causing an accumulation of fluid in various parts of the body congestive heart failure
