Human Circulatory System Anatomy Diagram | Medical Education Resource #3262914 (License: Personal Use)

This medical illustration depicts the full human circulatory system, with red vessels representing arteries carrying oxygen-rich blood from the heart, and blue vessels indicating veins returning deoxygenated blood. Key structures-including the heart, brain, kidneys, and peripheral circulation in limbs-are clearly shown to demonstrate systemic and pulmonary circulation pathways.

Used in educational websites, anatomy courses, health blogs, and medical textbooks to explain cardiovascular function; targets students, teachers, and patients seeking visual understanding of blood flow and organ perfusion.
