Human Heart Anatomy Diagram - Labeled Structure and Function Guide #1767106 (License: Personal Use)

This vintage-style line illustration depicts a cross-section of the human heart with 11 numbered labels identifying critical components including the superior/inferior vena cava (1, 2), right atrium (3), right ventricle (4), pulmonary artery (5), left atrium (7), left ventricle (9), aorta (10), and pulmonary veins (6, 8), along with the coronary sinus (11). Arrows indicate blood flow direction through the cardiac cycle. The image emphasizes structural relationships essential for understanding circulation and cardiac physiology.

Used in educational resources such as biology textbooks, medical training modules, and health websites to teach cardiovascular anatomy; ideal for students, educators, and healthcare professionals seeking foundational knowledge of heart structure and function.
