Name: Score:84 Multiple choice questions
Term 1 of 84
opening & closing of the cardiac valves is primarily dependent upon the
compliance of the chambers
resistance of the chambers
pressure difference in the chambers
amount of volume found in the chambers
Term 2 of 84
epicardium
the amount of tension in a muscle after it begins to contract (systole); in heart muscle, it is
determined by aortic pressure
double-layered membrane surrounding the heart - serves as protection and support
carry oxygenated blood away from the heart (with the exception of pulmonary arteries,
which carry deoxygenated blood away from the heart)
outermost layer of the heart - forms a protective cover for the heart and the coronary
arteries run along this layer
Definition 3 of 84
normal pacemaker of the heart, inherent rate of 60-100 BPM, located in the right atrium,
corresponds to the P wave on the ECG due to atrial depolarization
mean arterial pressure (MAP)
blood flow through the heart
PR interval normal value
sinoatrial node (SA node)
,Term 4 of 84
posterior (dorsal)
large vein that carries oxygen-poor blood to the right atrium from the lower half of the
body
near or on the back of the body
large vein that brings oxygen-poor blood from the upper part of the body to the right
atrium
ventricular depolarization (contraction)
Definition 5 of 84
carries deoxygentated blood from the right ventricle to the lungs
pulmonic valve
3 coronary arteries of the heart
left atrium
pulmonary artery
Term 6 of 84
blood flow through the heart
SVC/IVC —> right atrium —> tricuspid valve —> right ventricle —> pulmonic valve —>
pulmonary arteries —> lungs —> pulmonary veins —> left atrium —> mitral valve —> left
ventricle —> aortic valve —> aorta —> body
aorta —> arteries —> arterioles —> capillaries —> venules —> veins —> vena cava —> right
atrium
normal pacemaker of the heart, inherent rate of 60-100 BPM, located in the right atrium,
corresponds to the P wave on the ECG due to atrial depolarization
secondary pacemaker, inherent rate of 40-60 BPM, located in lower portion of right atrium,
AKA the "gatekeeper", corresponds to the PR segment on the ECG
, Definition 7 of 84
carry oxygenated blood away from the heart (with the exception of pulmonary arteries, which
carry deoxygenated blood away from the heart)
left atrium
preload
pulmonary veins
arteries
Definition 8 of 84
epicardium, myocardium, endocardium
3 layers of the heart
Ta wave represents
QRS complex represents
equation for pulse pressure
Definition 9 of 84
ventricles contract and expel blood
superior
systole
QRS complex represents
QRS interval
