In your wordstell how blood flows through the heart and to other parts of body?

Blood flows through the heart in a specific pathway: it enters the right atrium from the body via the superior and inferior vena cavae, then moves to the right ventricle, which pumps it to the lungs through the pulmonary arteries for oxygenation. Oxygen-rich blood returns to the left atrium via the pulmonary veins, flows into the left ventricle, and is then pumped out to the rest of the body through the aorta. This continuous cycle ensures that oxygen and nutrients are delivered to tissues while waste products are removed.
