This anatomical diagram highlights the four chambers of the heart-right atrium, right ventricle, left atrium, and left ventricle-with distinct colors and directional arrows indicating blood flow. Key structures such as the tricuspid and mitral valves, pulmonary artery, and aorta are clearly labeled to aid understanding of systemic and pulmonary circulation. Dotted lines denote internal septa separating oxygenated and deoxygenated blood pathways.

Used in medical education, biology textbooks, health websites, and patient information resources to explain cardiac physiology; matches user intent for learning heart structure, circulation, or preparing for exams.
