Human Circulatory System Diagram - Anatomy & Function Guide #3627545 (License: Personal Use)

This educational infographic depicts the full human circulatory system with anatomical accuracy, using red for arterial (oxygenated) blood and blue for deoxygenated blood. Key components-including the heart, brain, lung, liver, bowel, and limb vessels-are clearly labeled, along with capillaries illustrating microcirculation. The diagram supports understanding of systemic and pulmonary circulation loops.

Used in biology, health education, or medical websites to teach cardiovascular anatomy; ideal for students, teachers, or patients seeking visual explanation of blood flow pathways and organ perfusion.
