Human Heart Anatomy Diagram - Labeled Structure for Medical Education #1821158 (License: Personal Use)

This black-and-white line drawing presents a cross-sectional view of the human heart with 15 numbered labels identifying critical components such as the superior vena cava (1), pulmonary artery (2), aorta (9), left and right atria (5, 11), left and right ventricles (6, 12), mitral and tricuspid valves (7, 13), and coronary vessels (14, 15). The diagram emphasizes spatial relationships and functional anatomy essential for understanding cardiac physiology. Dotted lines indicate internal septa and valve positions for clarity.

Used in medical textbooks, online anatomy courses, patient education materials, and clinical training modules; serves users seeking foundational knowledge of cardiovascular structure, often before studying physiology or pathology.
