Final answer:
Blood flows through the heart in two separate loops: the left side loop and the right side loop. The left side collects oxygen-rich blood from the lungs and pumps it to the rest of the body, while the right side collects oxygen-poor blood from the body and pumps it to the lungs for oxygenation.
Step-by-step explanation:
The blood flows through the heart in two separate loops, known as the 'left side loop' and the 'right side loop'. The left side of the heart collects oxygen-rich blood from the lungs and pumps it to the rest of the body.
The right side of the heart collects oxygen-poor blood from the body and pumps it to the lungs for oxygenation. This creates a continuous cycle of blood flow through the heart, delivering oxygen to the body's cells and returning oxygen-poor blood back to the heart.
