The term ________ refers to blockage in the coronary circulation.
coronary artery disease
Thick projections of muscle in the ventricles that anchor chordae tendineae are called
Papillary muscles
Is an important ridge of muscle extending horizontally around the right ventricle from the interventricular septum to the base of the anterior papillary muscle containing part of the conducting system.
Moderator band

or by increasing______
end systolic volume; SV, EF, HR
If the force of ventricular contraction increases, what will happen to the end-systolic volume?
Decrease
End-systolic volume is defined as the
