cardiovascular system
aorta
great artery
cardium
heart
how to remember diastole
d=dilate
what kind of blood does a vein have
deoxygenated
tunica intima
elastic tissue; friction and expand
layers within the capillary
1 thin = diffusion
where does the capillary deliver blood
to every organ
where does the vein deliver blood
to the heart
LUB
tricuspid and bicuspid valves close, during systole
epi
upon, on
what contains the largest tunica media (muslce)
vein
diastole
ventricles FILL with blood (relax)
systole
ventricles SEND blood (contract)
layers within the vein
3 thick layers
layers within the artery
3 thin layers
what is sound 2 (s2) of the heart
DUB
what kind of blood does the right side of the heart have
Deoxygenated
what is sound 1 (s1) of the heart
LUB
where does the artery deliver blood
away from the heart
bicuspid (mitral) valve
between left atrium and ventricle; prevents back flow into the left atrium
aortic semilunar valve
between left ventricle and aorta; prevents back flow into the left ventricle
tricuspid valve
between right atrium and ventricle; prevents back flow into the right atrium
pulmonary semilunar valve
between right ventricle and pulmonary trunk; prevents back flow into the right ventricle
inferior vena cava
brings oxygenated blood back to the heart from the lower body
superior vena cava
brings oxygenated blood back to the heart from the upper body
left pulmonary artery
carries deoxygenated blood to the lungs
right pulmonary artery
carries deoxygenated blood to the lungs
pulmonary trunk
carries deoxygenated blood to the pulmonary arteries
left and right pulmonary veins
carries oxygenated blood to the left atrium
tunica externa
collagen and elastic tissue; protection from damage
pressure within the artery
high (ventricles contracting)
endo
inner
diameter of the vein
large (low pressure)
what side is the aortic semilunar valve on
left
what side is the bicuspid valve on
left
pressure within the capillary
low (singular layer)
diameter of the artery
medium
pressure within the vein
medium (contains valves)
myocardium
middle layer, moves blood by contracting
myo
muscle
chordae tendineae
opens and closes valves; bicuspid and tricuspid only
epicardium
outer fluid filled layer, protects, lubricates
what kind of blood does an artery have
oxygenated
what type of blood does the left side of the heart have
oxygenated
what kind of blood does a capillary have
oxygenated and deoxygenated
papillary muscle
pull on the chordae tendinae to move the valves
DUB
pulmonary and aortic semilunar valves close, during diastole
left atrium
receives blood from the lungs
right atrium
receives blood from upper and lower body
what side is the pulmonary semilunar valve on
right
what side is the tricuspid valve on
right
how to remember tricuspid valve
roll tide
trabeculae carneae
rough/uneven surface, decrease suction, contracts to pull the chordae tendineae downward
how to remember systole
s = send/squeeze
left ventricle
sends blood to body
right ventricle
sends blood to lungs
interventricular septum
separates the ventricles and the oxygenated and deoxygenated blood
diameter of the capillary
small
endocardium
smooth inner layer, lines the chambers and valves
tunica media
smooth muscle; push blood, prevent collapsing
why are the ventricles pushing the blood
so it can get where it needs to go
why do you want the valves to close
so the blood doesn't go backwards
descending aorta
supplies everything below the heart
ascending aorta
supplies oxygenated blood to everything above the heart
