This black-and-white anatomical illustration depicts the human heart’s four chambers (left/right atria and ventricles), major vessels (aorta, pulmonary artery, vena cava), and directional blood flow using arrows. It highlights the path of deoxygenated blood entering the right side and oxygenated blood exiting the left side-perfect for teaching cardiovascular physiology. The clean line art makes it suitable for coloring, labeling exercises, or digital learning modules.

Used in K-12 science curricula, medical student handouts, health literacy materials, and interactive anatomy websites; supports user intent to visualize or study cardiac circulation basics.
