Human Circulatory System Diagram - Anatomy & Key Blood Vessels #1499018 (License: Personal Use)

This medical illustration displays the full human circulatory system, with red vessels indicating arteries carrying oxygenated blood away from the heart and blue vessels representing veins returning deoxygenated blood. Major structures-including the aorta, carotid, brachial, femoral, and iliac arteries, as well as jugular, subclavian, and great saphenous veins-are clearly labeled. The heart is centrally positioned to show its role as the pump for systemic and pulmonary circulation.

Used in educational websites, medical textbooks, anatomy courses, and health portals to teach cardiovascular anatomy; ideal for students, educators, and healthcare professionals seeking visual reference for vessel identification and spatial relationships.
