Correct Answer is B
Explanation
A. Blood fills the left ventricle and empties the right: This refers to the ventricles, not the atria, so it is incorrect in the context of atrial diastole.
B. Both the left and right atrial chambers fill with blood: During atrial diastole, the atria relax and fill with blood from the veins (superior/inferior vena cava for the right atrium and pulmonary veins for the left atrium).
C. Blood fills the right atrium and empties the left: This is incorrect because both atria fill with blood during atrial diastole.
D. Both the left and right atria are emptied of blood: This describes atrial systole (contraction), not diastole.
