Human Circulatory System Diagram - Major Arteries and Veins Labeled #1499026 (License: Personal Use)

This anatomical diagram displays the full human circulatory system, clearly distinguishing arteries (in red) from veins (in blue) and labeling over 20 major vessels including the aorta, superior vena cava, pulmonary arteries, femoral artery, and great saphenous vein. Each vessel is precisely annotated with leader lines pointing to its location on a standard anterior human figure. The image serves as an educational tool for understanding systemic blood flow pathways from the heart to extremities and back.

Used in medical education, biology textbooks, online anatomy resources, and health websites to teach cardiovascular anatomy; matches user intent for learning or reviewing human vascular structures.
