Human Heart Anatomy Diagram - Right and Left Chambers, Aorta, and Blood Flow #2367988 (License: Personal Use)

This medical illustration depicts the four chambers of the human heart-right atrium, right ventricle, left atrium, and left ventricle-with clear labeling in Portuguese. Arrows indicate blood flow: deoxygenated blood enters the right atrium via vena cava, moves to the right ventricle, then to the lungs via pulmonary artery; oxygenated blood returns via pulmonary veins to the left atrium, then left ventricle, and exits through the aorta. The diagram highlights valve function and chamber separation using dotted lines and contrasting colors.

Used in educational contexts such as biology textbooks, medical training modules, or health literacy websites to explain cardiac anatomy and circulation. Matches user intent for learning heart structure, physiology, or preparing for exams.
