Human Heart Anatomy Diagram - Historical Medical Illustration #3281026 (License: Personal Use)

This finely detailed black-and-white engraving depicts a sagittal cross-section of the human heart, revealing the left and right atria and ventricles, interventricular septum, and major vessels. Hatching and stippling techniques indicate tissue density and structural boundaries, while handwritten-style French annotations (e.g., “d’”, “g”, “a”) point to specific regions. The illustration reflects pre-modern cardiac anatomy understanding, likely from a 19th-century medical textbook or atlas.
