What are the four chambers of the heart? -CORRECTANSWER Right atrium, Right
ventricle, Left atrium, Left ventricle.
Which valve is between the right atrium and ventricle? -CORRECTANSWER Tricuspid
valve.
Which valve is between the left atrium and ventricle? -CORRECTANSWER Mitral
(bicuspid) valve.
Which valves are semilunar? -CORRECTANSWER Pulmonary and aortic semilunar
valves.
What vessels bring deoxygenated blood to the right atrium? -CORRECTANSWER SVC,
IVC, coronary sinus.
What vessels bring oxygenated blood to the left atrium? -CORRECTANSWER
Pulmonary veins.
,Where does the pulmonary artery carry blood? -CORRECTANSWER From the right
ventricle to the lungs.
Where does the aorta carry blood? -CORRECTANSWER From the left ventricle to the
body.
What is pulmonary circulation? -CORRECTANSWER Blood from RV to lungs and back
to LA.
What is systemic circulation? -CORRECTANSWER Blood from LV to body and back to
RA.
What is coronary circulation? -CORRECTANSWER Blood flow to and from the heart
tissue.
What is the pacemaker of the heart? -CORRECTANSWER SA node.
What does the AV node do? -CORRECTANSWER Delays impulse so atria contract
first.
Path of cardiac conduction? -CORRECTANSWER SA node --> AV node --> Bundle of
His --> Purkinje fibers.
,What is the function of Purkinje fibers? -CORRECTANSWER Rapidly conduct impulses
to ventricles.
What does the P wave represent? -CORRECTANSWER Atrial depolarization.
What does the PR interval indicate? -CORRECTANSWER AV node delay.
What does the QRS complex represent? -CORRECTANSWER Ventricular
depolarization.
What does the T wave represent? -CORRECTANSWER Ventricular repolarization.
Which channel opens first in ECC? -CORRECTANSWER L-type Ca2+ channel in T-
tubules.
What triggers RyR channels? -CORRECTANSWER Calcium influx from L-type
channels.
What does calcium bind to for contraction? -CORRECTANSWER Troponin C.
What moves tropomyosin? -CORRECTANSWER Troponin after Ca2+ binding.
Which pump returns Ca2+ to SR? -CORRECTANSWER SERCA ATPase.
, Which exchanger removes Ca2+ from cell? -CORRECTANSWER Na+/Ca2+
exchanger.
What causes slow depolarization in SA node? -CORRECTANSWER Funny Na+
channels.
What causes threshold depolarization in SA node? -CORRECTANSWER T-type Ca2+
channels.
What causes upstroke in SA node AP? -CORRECTANSWER L-type Ca2+ channels.
What causes repolarization in SA node? -CORRECTANSWER K+ efflux.
Do SA nodal cells have a resting potential? -CORRECTANSWER No, they depolarize
continuously.
Resting potential of ventricular cells? -CORRECTANSWER -90 mV.
What ion causes phase 0 depolarization? -CORRECTANSWER Na+ influx.
What happens in phase 1? -CORRECTANSWER K+ efflux begins (transient).
