Human Circulatory System Diagram - Anatomy & Function Guide #1499029 (License: Personal Use)

This medical illustration depicts the full human circulatory system, including systemic and pulmonary circulation pathways. Major vessels such as the aorta, vena cava, carotid, femoral, and iliac arteries and veins are clearly labeled, alongside associated organs like the heart, lungs, liver, and kidneys. The diagram uses standard anatomical color coding-red for oxygenated arterial flow and blue for deoxygenated venous return-to enhance educational clarity.

Used in biology, anatomy, and health education contexts-on educational websites, e-learning platforms, textbooks, or medical reference pages-targeting students, teachers, and healthcare learners seeking visual reinforcement of cardiovascular anatomy.
