Human Circulatory System Diagram - Labeled Anatomy for Education & Medical Reference #2177641 (License: Personal Use)

This medical illustration depicts the full human circulatory system, with numbered labels identifying major arteries (e.g., aorta, carotid, femoral) and veins (e.g., jugular, vena cava, saphenous), centered around the heart. The diagram uses color-coding-blue for deoxygenated blood pathways and red for oxygenated flow-to clarify systemic circulation. It includes superficial and deep vascular structures from head to feet for anatomical clarity.

Used in educational settings (biology/medicine textbooks, online courses), patient education materials, and clinical reference guides; serves users seeking visual understanding of vascular anatomy for study, diagnosis, or teaching.
