Human Heart Anatomy Diagram - Labeled Structure & Function Guide #1404460 (License: Personal Use)

This medical illustration depicts a sagittal cross-section of the human heart, clearly labeling the right and left atria and ventricles, the tricuspid and mitral valves, pulmonary artery, aorta, superior/inferior vena cava, and pulmonary veins. The color-coding distinguishes oxygenated (red) from deoxygenated (blue/purple) blood flow pathways. Ideal for educational use in biology, medicine, or patient-facing health resources.

Used in medical textbooks, online health education platforms, anatomy courses, and patient brochures to explain cardiac structure and circulation; matches user intent for learning or teaching heart physiology.
