The 300129 Animated Human Heart is a detailed, animated representation of the human heart, often used for educational and medical purposes. It visually depicts the heart’s structure, including its four chambers—right atrium, right ventricle, left atrium, and left ventricle—as well as the flow of blood through the heart and its connection to the circulatory system. The animation typically shows the heart’s pumping action, the movement of oxygenated and deoxygenated blood, and how the heart works in coordination with the lungs and body. This animation is a useful tool for understanding the heart’s function, anatomy, and the process of blood circulation.
