Human Heart Anatomy Diagram - Labeled Structure & Function Guide #1664337 (License: Personal Use)

This black-and-white line drawing presents a sagittal cross-section of the human heart, clearly labeling 16 anatomical features including the superior vena cava (1), pulmonary artery (13), left atrium (10), mitral valve (9), left ventricle (8), aorta (14), and coronary sinus (5). The diagram emphasizes spatial relationships between chambers, valves, and vascular connections essential for understanding cardiac circulation. Shading indicates muscle thickness and chamber boundaries for visual clarity.

Used in medical education, anatomy textbooks, online learning modules, and patient education resources to explain heart structure and function; targets students, healthcare professionals, and curious learners seeking foundational cardiovascular knowledge.
