Final answer:
Option C correctly lists the normal path blood takes as it flows through the heart, going from right atrium to right ventricle, lungs, left atrium, left ventricle, and then to the body.
Step-by-step explanation:
The correct sequence for the flow of blood through the heart is: the right atrium receives deoxygenated blood from the body, pumps it into the right ventricle, which then sends it to the lungs for gas exchange. Oxygenated blood returns to the left atrium, goes into the left ventricle, and is then pumped out to the body. Therefore, the correct answer to the question is C. Right atrium, right ventricle, lungs, left atrium, left ventricle, body.
