Human Circulatory System Diagram - Arteries, Veins, and Heart Anatomy #281843 (License: Personal Use)

This stylized anatomical diagram depicts the full human circulatory pathway, emphasizing major arteries (red) and veins (blue) extending from the heart through the head, torso, arms, and legs. The heart is shown centrally with pulmonary circulation to the lungs (pink), while the liver and other organs are implied by vessel branching. The clean line-art style enhances educational clarity without overwhelming detail.

Used in biology textbooks, health education websites, and medical training materials to explain systemic and pulmonary circulation; targets students, teachers, and patients seeking foundational cardiovascular knowledge.
