Human Heart Anatomy Diagram - Labeled Chambers and Blood Flow #2268177 (License: Personal Use)

The image is a cross-sectional anatomical illustration of the human heart, color-coded to distinguish deoxygenated (blue) and oxygenated (red) blood pathways. Key structures-right atrium, right ventricle, left atrium, and left ventricle-are clearly labeled with arrows indicating unidirectional blood flow through the heart’s chambers and valves. The depiction emphasizes functional anatomy relevant to cardiovascular physiology and clinical understanding.

Used in educational contexts such as biology textbooks, medical training modules, health websites, and patient education materials; matches user intent for learning basic cardiac structure, preparing for exams, or explaining heart function to non-specialists.
