The heart, nestled between the lungs and protected by the rib cage, serves as a powerful pump ensuring blood flow throughout the body. This systemic flow delivers oxygen and nutrients to cells and removes waste. Additionally, the heart manages pulmonary flow, sending blood to the lungs for oxygenation before distributing it to the body. Lastly, the heart's own cells are nourished by coronary blood vessels, part of the systemic flow.

Explore the roles of arteries and veins in the circulatory system. Uncover common misconceptions about oxygenated and deoxygenated blood, and learn the true distinction: arteries carry blood away from the heart, while veins transport blood towards the heart. Delve into the high-pressure nature of arteries and the low-pressure, high-volume characteristics of veins.
