Human Heart Anatomy Diagram - Interior View with Blood Flow Labels #2367883 (License: Personal Use)

The diagram presents a cross-sectional view of the human heart, highlighting the right and left atria and ventricles, the tricuspid and mitral valves, and the pulmonary and systemic circulation pathways. Arrows indicate blood movement-from the body to the right atrium, through the lungs to the left atrium, and out to the body via the aorta-while dotted lines denote deoxygenated blood and solid arrows show oxygenated flow. Key structures like the septum, pulmonary artery, and vena cava are clearly annotated for educational clarity.

Used in biology and medical education websites, textbooks, and e-learning modules to teach cardiovascular system fundamentals; matches user intent for visual learning, exam prep, or classroom instruction on heart function.
