Human Circulatory System Diagram - Anatomy & Function Overview #3703524 (License: Personal Use)

The image depicts a full-body schematic of the human circulatory system, with the heart centrally located and major vessels radiating outward. Arteries are shown in red, carrying oxygenated blood away from the heart, while blue veins return deoxygenated blood. Key structures like the aorta, vena cava, pulmonary vessels, and peripheral circulation in limbs are clearly represented for educational clarity.

Used in medical education, biology textbooks, health websites, and patient-facing resources to explain cardiovascular anatomy; ideal for users seeking foundational knowledge about how blood circulates through the body.
