Human Heart Anatomy Diagram - Labeled Chambers, Valves & Blood Vessels #1203183 (License: Personal Use)

This medical illustration depicts the human heart in anterior view, highlighting four chambers (right atrium, right ventricle, left atrium, left ventricle), four valves (tricuspid, pulmonary, mitral, aortic), and major vessels including the superior/inferior vena cava, pulmonary arteries/veins, and aorta. Color coding distinguishes oxygenated (red) from deoxygenated (blue) blood flow, and arrows indicate direction of circulation. The numbered labels correspond to standard anatomical references for teaching and clinical review.

Used in biology, anatomy, and physiology educational resources-such as textbooks, online courses, and medical training modules-to help learners identify cardiac structures and understand blood flow pathways. Matches user intent for visual study aids, exam preparation, or classroom instruction.
