which ventricle ejets more blood

Which of the following structures acts to carry electrical impulse to the ventricles?       chordae tendineae     Purkinje fibers     papillary muscles     SA node

Which valves separate the left atrium from the left ventricle

isovolumetric contraction isovolumetric relaxation ventricular filling ventricular ejection closed rises S1 drops depolarize S2 The first phase of the cardiac cycle is . This is when a lot of blood is in the atria, which causes atrial pressure to be higher than the ventricles. The atrioventricular valves open, and blood moves from the atria to the ventricles. At the end of this phase, the atria contract to maintain pressure and blood flow into the ventricles. As blood leaves the atria, the pressure in the atria As blood enters the ventricles, the pressure in the ventricles Towards the end of this phase, the pressure in the ventricles will exceed the pressure in the atria. At this point, the heart enters the second phase of the cardiac cycle: At this point, the AV valves shut, and we hear . The atria repolarize and the ventricles (due to the QRS complex of the ECG), causing ventricular contraction. Although contracting, it is not yet moving blood into the arteries. All 4 heart valves…

What is difference between atrial fibrillation and atrial flutter

Congestive Heart Failure Why is this related to a valve or ventricular insufficiency? Where does the blood back up when it can't get out of the left ventricle?

Conduction through which of the following occurs directly after SA node is initiated. -AV node -Atria -Purkinje fibers -SA node -bundle of HIS

ncreasing preload __________ ventricular contractility.     decreases     has no effect on     increases

Does all arteries carry oxygensted blood

When the right ventricle is pumping to the lungs which valve is there ?
