through which valve will blood flow when leaving the right atrium?

• pulmonary semilunar valve

• bicuspid valve

• tricuspid valve

• aortic semilunar valve

what is the function of the heart valves?

• allows blood to flow from one chamber to the next

• synchronizes blood flow through chambers on each side of the heart

• regulates blood pressure in the chambers of the heart

• prevents backflow of blood

what part of the heart's intrinsic system carries impulses into the interventricular septum?

• purkinje fibers

• bundle branches

• atrioventricular AV bundle

• atrioventricular AV node

what term refers to the contraction of the heart?

• systole

• diastole

• cardiac cycle

• stroke volume SV

which of these will decrease heart rate?

• sudden drop in blood pressure BP

• secretion of epinephrine

• stimulation by vagus nerves

• increase in body temperature

the partition where the bundle branches are located is called the
