Human Heart Anatomy: Surface and Internal Structure Diagram #1499039 (License: Personal Use)

This dual-view medical illustration presents both the external surface anatomy and a sagittal cross-section of the human heart. The left side shows major vessels like the aorta, pulmonary artery, and vena cavae, while the right side reveals internal structures such as the bicuspid (mitral) and tricuspid valves, chordae tendineae, interventricular septum, and myocardial layers. Color-coding distinguishes oxygenated (red) from deoxygenated (blue) blood pathways.

Used in medical textbooks, anatomy courses, patient education materials, and health websites to teach cardiac structure and function; ideal for students, clinicians, and patients seeking visual understanding of heart physiology.
