Human Heart Blood Flow Diagram - Anatomy and Circulation Explained #1821171 (License: Personal Use)

This anatomical illustration depicts the path of blood through the human heart, highlighting deoxygenated blood (blue) entering via the superior and inferior vena cava into the right atrium, then right ventricle, and pumped to the lungs via the pulmonary artery; oxygenated blood (pink) returns via pulmonary veins to the left atrium, left ventricle, and exits through the aorta. Arrows indicate flow direction, and key structures-including atria, ventricles, and major vessels-are clearly labeled for educational clarity.

Used in medical education, physiology textbooks, or health websites to teach cardiovascular circulation; matches user intent for understanding heart function, preparing for exams, or patient education on cardiac health.
