Question 1
In what phase do the semilunar valves open allowing blood to eject into the pulmonary trunk and aorta?
Question 2
What heart sound is associated with the closing of the semilunar valves?
Question 3
What feature of aortic pressure occurs shortly after semilunar valves close?
Question 4
What percentage of ventricular filling occurs passively before the atrial contraction in mid to late ventricular diastole?
Question 5
What occurs during isovolumetric relaxation in terms of the heart valves?
Question 6
What pressure relationship allows for AV valves to open during mid to late ventricular diastole?
Question 7
During which phase of the cardiac cycle do AV valves open to allow passive blood flow into the ventricles?
Question 8
What EKG component indicates the repolarization of the ventricles?
Question 9
During ventricular ejection, what is the pressure relationship between the ventricles and the arterial system?
Question 10
What EKG component represents ventricular depolarization?
Question 11
Which heart sound corresponds with the closing of the AV valves?
Question 12
During which phase of the cardiac cycle are all cardiac valves closed but volume remains constant due to increasing pressure?
Question 13
What EKG component indicates atrial depolarization?
Question 14
What is the average duration of the entire cardiac cycle?
Question 15
During which phase does blood distribute to the systemic, pulmonary, and coronary circuits while the ventricles begin to relax?
