Final answer:
Blood flows through the heart in two separate loops, the right side loop and the left side loop. The right side of the heart collects oxygen-poor blood from the body and pumps it to the lungs, while the left side carries the oxygen-rich blood back from the lungs and pumps it to the rest of the body.
Step-by-step explanation:
Blood flows through the heart in two separate loops: the right side loop and the left side loop. The right side of the heart collects oxygen-poor blood from the body and pumps it to the lungs. In the lungs, carbon dioxide is released and oxygen is obtained by the blood. The left side of the heart carries the oxygen-rich blood back from the lungs and pumps it to the rest of the body.
