Human Heart Anatomy Diagram - Arteries, Veins, and Major Vessels #3045676 (License: Personal Use)

This schematic shows the human heart in anterior view, with red vessels representing oxygen-rich arterial blood (e.g., aorta, pulmonary veins) and blue vessels indicating deoxygenated venous return (e.g., vena cava, pulmonary arteries). Key structures like the left and right atria, ventricles, and major outflow tracts are visible, emphasizing functional anatomy for learning cardiovascular physiology.

Used in educational websites, medical textbooks, and health blogs to explain cardiac structure and circulation; targets students, educators, and patients seeking foundational knowledge of heart anatomy.
