Total questions: 8
Worksheet time: 5mins
What is systole?
Relaxation in a chamber in the heart
Contraction in a chamber of the heart
a complete heartbeat
Dilation in the heart
What is the cardiac cycle?
A complete heartbeat
Amount of blood the heart can pump
How fast blood is pumped through the heart
Systemic arterial pressure
Which step belongs to atrial systole?
blood is pushed through systemic and pulmonary circuits and toward the atria
semilunar valves open as a result of pressure
contraction exerts enough pressure to close the AV valves, but not enough to open semilunar valves
small amount of blood enters relaxed ventricles
Choose the correct order of the cardiac cycle
Atrial systole, ventricular diastole, atrial diastole, ventricular systole
Ventricular diastole, ventricular systole, atrial diastole, atrial systole
Atrial systole, ventricular systole, atrial diastole, ventricle diastole
what is diastole?
Contraction in a chamber of the heart that pushes blood
Blood leaving the heart and going to the body
Relaxation in a chamber of the heart that fills with blood
Which steps belong to Ventricular Systole?
Goes through alternating waves of systole and diastole
Contraction exerts enough pressure to open AV valves, but pressure is not high enough to open semilunar valves
Rising pressure opens semilunar valves
Heart chamber relaxes and fills with blood
What causes the "Lubb" sound?
AV valves closing
Buildup of pressure
Ventricles relaxing
What causes the "dupp" sound?
systole
ventricles relaxing and the semilunar valves open
AV valves closing
the complete heartbeat
