_____ This valve prevents backflow from the right ventricle to the right atrium.
_____ This is the name for the pressure in the arteries when the ventricles are contracting.
_____ This ion imbalance will increase the contractility of the heart.
_____ , _____, _____, _____ These factors have a positive chronotropic and/or positive inotropic effect on the
heart.
_____ At this time all the chambers of the heart are relaxed.
_____ This is the name for the endothelium lining the heart chambers.
_____ This is the other name for the end diastolic volume.
_____ This is the name for a fixed blood clot in an artery.
_____ This is the pressure in the aorta that the left ventricle has to overcome to eject blood.
_____ This is the portion of the conducting system that delays the wave of depolarization one tenth of a second.
_____ This is the sound made as blood becomes turbulent due to the closing of the semilunar valves.
_____ This is the amount of blood pump from the left ventricle with each beat.
_____ This is the name for a factor that increases the strength of contractility of the heart.
_____ This valve prevents backflow between the aorta and the left ventricle.
_____ This chamber has the thickest walls due to the increased resistance the blood must travel.
_____, _____, _____ These factors have a negative chronotropic and/or negative inotropic effect on the heart.
2.
If the right ventricle has greater stroke volume than the left ventricle pulmonary edema/systemic edema will
result. If the left ventricle has greater stroke volume than the right ventricle pulmonary edema/systemic edema
