Human Heart Anatomy Diagram - Structure, Chambers, and Blood Flow #3302248 (License: Personal Use)

This stylized anatomical illustration depicts the four chambers of the human heart-right atrium, right ventricle, left atrium, and left ventricle-along with key structures such as the aorta, pulmonary artery, superior/inferior vena cava, and pulmonary veins. Red areas represent oxygenated blood flowing from lungs to the body via the left side, while blue indicates deoxygenated blood returning from the body to the lungs via the right side. Valves like the mitral and tricuspid are subtly indicated by circular shapes within chambers.

Used in educational websites, medical textbooks, anatomy courses, and health outreach materials to teach cardiovascular physiology. Matches user intent for visual learning about heart structure, circulation, or preparing for exams like NCLEX or MCAT.
