WebIn the diastolic phase, it has to relax very quickly after each contraction so as to quickly fill with the oxygenated blood flowing from the pulmonary veins. Likewise in the systolic phase, the left ventricle must contract rapidly and forcibly to pump this blood into the aorta, overcoming the much higher aortic pressure. ... Left ventricular ... WebDiastole is the longer of the two phases so that the heart can rest between contractions. Which is correct during each cardiac cycle? During a cardiac cycle, each ventricle pumps out approximately 70mL of blood , thus, both the ventricles pump out same volume of blood in each cardiac cycle.

"WebFeb 3, 2024 · Diastolic Dysfunction. Ventricular filling in diastole relies on both a compliant ventricle and a pressure gradient between the left atrium and left ventricle (LV). In the early phase of diastole, active ventricular relaxation helps to generate this gradient by actively sucking blood into the ventricle via elastic recoil. " - Diastolic phase of ventricles
