Which of the following is false regarding the isovolumetric relaxation phase of the cardiac cycle? Group of answer choices There is no change in the volume of blood in the ventricles. The Semilunar valves close . The ventricles are in early diastole. The blood in the aorta and pulmonary trunk will flow back into the ventricles.

Which of the following statements about the cardiac cycle is TRUE? Multiple Choice The duration of systole is greater than that of diastole in a subject at rest. During isovolumetric ventricular relaxation, blood flows from the atria into the ventricles. Closure of the atrioventricular valves occurs at the beginning of ventricular systole. The QRS complex occurs at approximately the same time as the closure of the semilunar valves. The first valves to go from closed to open after the atrial kick are the atrioventricular valves.
