- 19. Multiple Choice
what happen in the first and second phase of ventricular systole?
in the first phase, the right ventricle contracts. while in the second phase, the left ventricle contracts
in the first phase, the left ventricle contract. while in the second phase, the left ventricle contracts
in the first phase, pressure from ventricle pumped out the blood. in the second phase, pressure from ventricle close the AV valves
in the first phase, pressure from ventricle close the AV valves. in the second phase, pressure from ventricle pumped out the blood
- 20. Multiple Choice
why is it important for signal conduction in heart to stop for a while in AV node?
to prevent atrium and ventricle from contracting at the same time
to prevent blood too much flowing from atrium to ventricle
to make sure that all valves are open before blood sent out from heart
to make sure there is enough time for atrium to receive blood from veins
