Human Heart Anatomy Diagram - Chambers, Valves, and Blood Flow Explained #3365124 (License: Personal Use)

This diagram depicts the four chambers of the human heart-right atrium, right ventricle, left atrium, and left ventricle-along with the four major valves: tricuspid, pulmonary, mitral, and aortic. Arrows indicate the direction of blood flow from systemic veins (superior/inferior vena cava) into the right side, through the lungs via pulmonary arteries/veins, and into the left side before ejection into the aorta. The color-coding distinguishes oxygenated (red/pink) from deoxygenated (blue/purple) blood.

Used in medical education, physiology textbooks, online learning modules, and patient education resources to explain cardiac anatomy and circulation. Matches user intent for visual learning, exam preparation, or clinical reference.
