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
