Human Circulatory System Diagram - Anatomy & Function Overview #3627531 (License: Personal Use)

This simplified anatomical illustration depicts the major pathways of the human circulatory system, including the heart at the center, systemic arteries branching to limbs and head, and returning veins. The diagram uses color-coding-red for oxygenated blood flow (arteries) and blue for deoxygenated blood (veins)-to aid visual learning. Though stylized, it accurately reflects core vascular structures essential for understanding cardiovascular physiology.

Used in educational websites, biology textbooks, and health literacy resources to teach basic cardiovascular anatomy; targets students, teachers, and general audiences seeking foundational knowledge of how blood circulates through the body.
