Human Heart Anatomy Diagram - Arteries, Veins, and Major Structures #1347550 (License: Personal Use)

This anatomically accurate 3D illustration depicts the human heart with vivid color-coding: red vessels represent oxygen-rich arterial circulation (including the aorta and coronary arteries), while blue vessels indicate deoxygenated venous return (such as the superior/inferior vena cava and pulmonary veins). The image clearly shows the heart’s external surface, major chambers, and vascular network, making it ideal for teaching cardiovascular physiology.

Used in medical education websites, anatomy textbooks, health blogs, and patient-facing resources to explain heart structure and circulation; matches user intent for learning or visualizing cardiac anatomy.
