Step 1
Identify the correct pathway
Answer
In the cardiac cycle, blood returns from the body to the heart via the vena cava, entering the right atrium first. The pathway proceeds from the right atrium to the right ventricle, then to the lungs for oxygenation, before returning to the left atrium, and finally pumping into the left ventricle to circulate throughout the body. Therefore, the correct answer is:
C Right atrium – right ventricle – left atrium – left ventricle
