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.
Learn about the important functions of the heart in the cardiovascular system, including systemic and pulmonary blood flow, coronary vessels, and cell nourishment. Understand how blood flow ensures oxygen delivery, waste removal, and cell health.
