Answer Choices:
Both the left and right atrial chambers fill with blood.
🢐 During atrial diastole, both the right atrium and the left atrium are in a relaxed state.
🢐 This relaxation allows blood to flow into the atria from the vena cavae on the right side and the pulmonary veins on the left side.
🢐 Atrial diastole is essential for ensuring that the atria are filled and ready for the next contraction (atrial systole).
🢐 This phase occurs while the ventricles are contracting during ventricular systole.
🢐 Thus, both atria fill with blood during atrial diastole, preparing for the next cardiac cycle.
