Human Cardiovascular System Diagram - Anatomy & Blood Flow Pathway #2351384 (License: Personal Use)

This medical illustration depicts the full circulatory pathway, highlighting oxygen (O₂) uptake in the lungs and carbon dioxide (CO₂) removal, with directional arrows indicating blood flow through the right and left ventricles, pulmonary artery/vein, carotid artery, and systemic vessels. Key structures-including the aorta, vena cava, jugular vein, and pulmonary circulation-are clearly labeled for educational clarity. The diagram uses color coding (blue for deoxygenated, red for oxygenated blood) to reinforce physiological concepts.

Used in anatomy textbooks, medical education websites, and health portals to teach cardiac physiology and circulation; targets students, educators, and patients seeking to understand how the heart and lungs collaborate in gas exchange.
