Human Circulatory System Diagram - Labeled Anatomy for Science Education #3894188 (License: Personal Use)

This educational infographic displays the full human circulatory system with red arteries (oxygenated blood) and blue veins (deoxygenated blood), highlighting major structures such as the aorta, vena cavae, pulmonary arteries/veins, carotid arteries, and femoral artery. It includes schematic diagrams of the pulmonary and systemic circuits, capillary gas exchange sites in lungs and tissues, and cross-sections of the heart with atria and ventricles labeled. Additional views show anterior full-body vasculature and line-art outlines for coloring or study aids.

Used in K-12 and college biology classrooms, medical training resources, and health education websites to teach cardiovascular anatomy and blood flow pathways; ideal for lesson plans, flashcards, worksheets, and interactive learning modules where visual clarity and labeling accuracy are essential.
