Cardiovascular System TERMS Flashcards
valve
prevents blood from flowing backward
valves in heart
pulmonary tricuspid aortic mitral
vena cava
superior, inferior veins through which de-oxygenated blood enters right atrium
pulmonary artery
carries blood to lungs where they pick up oxygen
pulmonary veins
bring oxygenated blood into left atrium
aorta
main artery that distributes oxygenated blood
coronary arteries
branch off of aorta and supply heart with oxygenated blood
carotid arteries
arteries located in neck supply brain with blood
brachial arteries
arteries located in arm
radial artery
artery located along the radius in the arm
femoral arteries
arteries located in the legs
arterioles
smallest arteries
capillaries
tiniest blood vessels which exchange nutrients, gas, wastes in body
venules
vessels that allow blood to return to veins from capillaries
sinoatrial node
heart’s pacemaker
atrioventricular node
conducts impulses to atrioventricular bundle (bundle of His)
atrioventricular bundle (bundle of His)
fibers that conduct impulses traveling to the ventricles
