Human Heart Anatomy Diagram - Chambers, Valves, and Blood Flow Explained #1664349 (License: Personal Use)

This educational illustration depicts a sagittal view of the human heart, distinguishing deoxygenated blood flow (purple/blue side) from oxygenated blood flow (red side). Key structures-including the right atrium, right ventricle, tricuspid valve, left atrium, left ventricle, bicuspid (mitral) valve, and semilunar valves-are precisely labeled with arrows indicating blood movement toward the lungs and body. The diagram highlights how valves prevent backflow and ensure unidirectional circulation.

Used in medical education, biology textbooks, health websites, and patient-facing materials to explain cardiac anatomy and physiology; matches user intent for learning or teaching heart structure and function.
