cardiovascular system Flashcards
apex
inferior part-points toward left hip
base
superior part- points toward right shoulder
pericardium
sac surrounding the heart
myocardium
cardiac muscle layer of heart wall
endocardium
lines heart chambers
atria
heart has two of these
ventricles
heart has two of these
interventricular septum
divides the two ventricles
superior venae cavae
vein in the body-top/toward head
inferior venae cavae
vein in body- bottom/toward feet
pulmonary arteries
carry blood to lungs
pulmonary veins
bring blood back to heart
aorta
major system artery
bicuspid valve
valve in heart with two points
tricuspid valve
valve in heart with three points
chordae tendineae
tiny white cords/heart strings anchors flap to walls of ventricles
pulmonary semilunar valve
lies between right ventricle and pulmonary artery
aortic semilunar valve
between left ventricle and aorta
coronary arteries
branch from base of aorta and surround the heart
cardiac veins
return deoxygenated blood to right atrium
pulmonary embolism
blockage of major blood vessel
stroke
blood supply to part of brain is cut off
myocardial infarction
heart attack
systole
phase of heart beat- muscle contracts and pumps blood from chambers into arteries
diastole
phase of heart beat- muscle relaxes and fills chambers with blood
carotid artery
supply blood to brain, neck and face
jugular vein
large vein in neck, carries blood from head and face
subclavian artery
forms brachiocephalic vein
brachial artery
blood vessel that flows down arm
thoracic aorta
supplies blood to lower half of body
renal vein
veins that drain kidneys
femoral artery
artery in femur
hepatic veins
veins in liver
axillary vein
vein in armpits
