Human Circulatory System Anatomy Diagram | Medical Education Resource #281903 (License: Personal Use)

The image displays a full-body anterior view with the cardiovascular system emphasized: oxygenated blood flows via red arteries from the heart to organs and extremities, while deoxygenated blood returns through blue veins. Key structures-including the aorta, pulmonary vessels, hepatic portal vein, and renal circulation-are clearly delineated against a translucent torso. The schematic uses color-coding and simplified anatomy for clarity without sacrificing clinical accuracy.

Used in medical textbooks, online anatomy courses, patient education portals, and health websites to explain blood flow, cardiovascular function, or pathology. Matches user intent for learning, teaching, or visual reference on human circulation.
