Circle of Willis Anatomy Diagram - Blood Flow Pathway in Human Circulation #3482283 (License: Personal Use)

This schematic highlights the Circle of Willis at the brain’s base, connecting internal carotid and vertebral arteries, and illustrates full systemic circulation-showing oxygenated (red) and deoxygenated (blue) blood paths through the heart, pulmonary circuit, hepatic portal system, renal filtration, and capillary exchange. Arrows indicate directional flow, with organ-specific vascular patterns emphasized for educational clarity.

Used in medical education, neurology, and physiology resources to teach cerebral perfusion, collateral circulation, and integrated cardiovascular-respiratory-renal function; targets students, residents, and healthcare professionals seeking visual reinforcement of hemodynamics.
