close-up view of a plastic anatomical model of the human heart, cut open to reveal internal structures. The focus is on the mitral valve, depicted with white chordae tendineae extending from the valve leaflets. The heart's chambers, including the right atrium and ventricle, are visible, with their characteristic textured surfaces. The model is made of red and yellow plastic, with some blue and grey accents indicating blood vessels. The background shows a glimpse of what appears to be a tiled wall and a metallic surface, suggesting a laboratory or educational setting. The camera moves slightly, providing different angles of the heart model.
