Human Heart Anatomy Diagram - Labeled Chambers, Valves, and Vessels #1664319 (License: Personal Use)

This medical illustration presents a sagittal section of the human heart, highlighting key anatomical features including the right and left atria and ventricles, the interventricular septum, and all four heart valves (tricuspid, pulmonary, mitral, and aortic). Major vessels such as the superior and inferior vena cava, pulmonary trunk, aorta, and pulmonary veins are precisely labeled with directional flow arrows. The diagram is designed for clarity in teaching cardiovascular physiology and anatomy.

Used in educational contexts-medical textbooks, online anatomy courses, healthcare training modules, and patient education materials-to help learners visualize and understand cardiac structure and blood flow pathways.
