Human Heart Anatomy Diagram - Educational Medical Illustration #3756417 (License: Personal Use)

This vibrant medical illustration depicts a sagittal cut of the human heart, clearly distinguishing the right side (deoxygenated blood, shown in deep red) from the left side (oxygenated blood, in bright blue). Major structures-including the atria, ventricles, aorta, pulmonary artery, and superior/inferior vena cava-are visually emphasized with bold outlines and color coding to aid learning. The image simplifies complex anatomy for clarity while preserving key physiological relationships.

Used in educational websites, biology textbooks, medical training modules, and patient education resources to explain cardiac anatomy and circulatory function; targets students, teachers, clinicians, and curious learners seeking visual understanding of heart physiology.
