This simplified anatomical illustration depicts the human circulatory system with red lines representing oxygenated arteries and blue lines indicating deoxygenated veins, all converging at the central heart. The diagram includes major vessels extending to the head, arms, torso, and legs, emphasizing systemic circulation pathways. It is designed for educational clarity rather than clinical precision.

Commonly used in K-12 science curricula, introductory biology courses, health education materials, and patient-facing infographics to explain how blood circulates through the body; matches user intent for visual learning and basic anatomy reference.
