Question

The isovolumic ventricular relaxation phase is the O amount of blood in the ventricles at the end of atrial systole just prior to ventricular contraction O intial phase of ventricular diastole when pressure in the ventricles drops below pressure in the two major artenies, the pulmonary trunk, and the aorta, and blood attempts to flow back into the ventricles, producing the dicrotic notch of the ECG and closing the two semilunar valves O amount of blood remaining in each ventricle following systole O initial phase of ventricular contraction, during which tension and pressure in the ventricle are increasing, but no blood is pumped or ejected trom the heart O percentage of blood thats pumped out of a filed ventricle with each neaitteat

Explanation / Answer

The isovolumetric relaxation phase is the initial phase of ventricular diastole when pressure in the ventricles drops below pressure in the two major arteries, the pulmonary trunk and the aorta , and blood attempts to flow back into the ventricles,producing the dicrotic notch of the ECG and closing the two semilunar valves. Aorta and pulmonary trunk closes because the pressure in them is still greater than the pressure in ventricles.
