Explanation:
When the muscles of the heart relax, it is referring to the diastolic phase of the cardiac cycle. During this phase, the heart is in a relaxed state and is filling with blood to prepare for the next contraction.
Option (a): Blood is pumped into the right auricle from all over the body
During the diastolic phase, the blood from all over the body is returning to the heart through the vena cava and is pumped into the right auricle. The right auricle is one of the chambers of the heart and its main function is to receive deoxygenated blood from the body. So, option (a) is correct.
Option (b): Blood flows from lungs into the left auricle
During the diastolic phase, the blood from the lungs is returning to the heart through the pulmonary veins and flows into the left auricle. The left auricle is another chamber of the heart and its main function is to receive oxygenated blood from the lungs. So, option (b) is correct.
Therefore, the correct answer is option (c) - both (a) and (b).
Option (d): Blood flows from the left ventricle to the rest of the body
Option (d) is not correct in this context as it describes the systolic phase of the cardiac cycle when the heart muscles contract and pump the blood from the left ventricle to the rest of the body. During the diastolic phase, the left ventricle is filling with blood from the left auricle and is not actively pumping blood out to the rest of the body.
