Human Circulatory System Diagram - Arteries, Veins, and Heart Anatomy #1498714 (License: Personal Use)

This diagram depicts the full human circulatory pathway, with red lines representing arteries (carrying oxygen-rich blood away from the heart) and blue lines indicating veins (returning oxygen-poor blood to the heart). Key structures-including the heart, lungs, liver, and major arterial/venous branches-are clearly outlined to support anatomical learning. The stylized, symmetrical layout enhances clarity while preserving physiological accuracy.

Used in educational websites, medical training modules, and health infographics to explain cardiovascular function; targets students, teachers, and patients seeking foundational anatomy knowledge.
