anatomy/physiology of heart quiz

atrial depolarization (atrial contracts blood to the ventrical

p-wave

pumping blood to body and lungs ventricles contracting out

QRS

ventricular relaxation (steady state)

T-wave

heart rate

R-R

rest

S-T

time it takes for action potential to spread through ventricles

Q-T

time it takes for SA node depolarization to spread through ventricles

P-R

120/80

normal blood pressure

blood pressure over 130/90

hyper tension

aorta

right ventricle

pulmonary trunk

left ventricle

(right side)

triscupid valve

(left side)

bicuspid valve

bicuspid valve is also called

mitral valve

right pulmonary artery

left pulmonary artery

right pulmonary veins

left pulmonary veins

drains deoxygenated blood

superior vena cava

drains deoxygenated blood

inferior vena cava

aortic valve

pulmonary valve

right atrium

left atrium

AV (atrioventricular) valves are

bicuspid and tricuspid valves

pulls on chordeae keeping valve flap tight

papillary muscle

interventricular septum

to keep valve flaps from flipping backward into the atria when ventricles squeeze

chordae tendineae

trabeculae carneae

why is the left ventricle thicker than the right ventricle?

it has to generate much more force to pump blood to the entire body

largest artery

aorta

arteries go which direction

AWAY

right ventricle pumps blood to your

lungs

atria recieves blood from

veins

veins pump blood into the

ventricles

semilunar valves

aortic valve and pulmonary valvr

apex

purpose of ECG

shows electrical activity of heart rate

atrial and ventricular fibrillation difference

ventricular more serious, no pulse and blood doesnt pump; atrial blood doesnt pump well

heart valves function

to open/close at the right time so blood can move from one chamber to another

blood goes from the body to the

vena cava

blood goes from the vena cava to the

right atrium

blood goes from the right atrium to the

tricuspid valve

blood goes from the tricuspid valve to the

right ventricle

blood goes from the right ventricle to the

pulmonary valve

blood goes from the pulmonary valve to the

pulmonary artery

blood goes from the pulmonary artery to the

lungs

blood goes from the lungs to the

pulmonary veins

blood goes from the pulmonary veins to the

left atrium

blood goes from the left atrium to the

left ventricle

blood goes from the left ventricle to the

aortic valve

blood goes from the aortic valve to the

aorta

blood goes from the aorta to the

body
