The human heart is a complex organ featuring an intricate network of blood vessels, chambers, and supporting structures that work together to maintain circulation throughout the body. This detailed anatomical illustration showcases the heart 's major vessels, arteries, and veins, along with its essential structural components, providing a comprehensive view of cardiac anatomy from an anterior perspective. The heart is a four-chambered muscular organ with a complex structure that allows it to efficiently pump blood throughout the body. It is divided into two halves—the right and left sides—each responsible for different aspects of circulation. In humans, the heart is approximately the size of a closed fist and is located between the lungs, in the middle compartment of the chest, called the mediastinum. [4]
