Human Heart Anatomy Diagram - Educational Medical Illustration #3092027 (License: Personal Use)

This educational illustration depicts the internal structure of the human heart with distinct color-coding: red for oxygenated blood pathways (e.g., pulmonary veins, aorta), blue for deoxygenated flow (e.g., vena cava, pulmonary artery), and purple for key structures like the pulmonary trunk. Valves-including mitral, tricuspid, aortic, and pulmonary-are shown in detail to clarify unidirectional blood flow. The artist’s signature “MARTIN” appears on the inferior vena cava.

Used in medical education websites, biology textbooks, patient-facing health resources, and interactive anatomy tools; serves users seeking foundational cardiovascular knowledge or visual aids for teaching.
