    Study Notes

    • The sketch illustrates the location of the heart in the body, surrounded by the ribs, between the two lungs.
    • Beneath the lungs and protected by the ribs lies a crucial muscle called the diaphragm.
    • Every cell in the body requires constant blood flow for oxygen and nutrients, as well as to remove waste like carbon dioxide.
    • Good blood flow ensures that waste is carried away, oxygen and nutrients are delivered, and cells thrive.
    • The heart acts as a powerful pump, ensuring systemic blood flow throughout the body.
    • Pulmonary flow is another essential function of the heart, involving pumping blood to and from the lungs for oxygenation and carbon dioxide removal.
    • The coronary vessels supply blood to the heart muscles, ensuring that the heart cells receive oxygen, nutrients, and waste removal, falling under systemic flow.
