Magnified Heart Model is an important teaching tool used in biology education to showcase the structure and function of the heart. This model is scaled up to the scale of the real heart, so that students can observe the various parts of the heart more clearly. In biology teaching, enlarging the heart model can help students intuitively understand the anatomical structure of the heart, learn the working principles of the heart, including blood circulation, the function of heart valves, and how the heart pumps blood. By observing and operating models, students can master the structure and function of the heart, and understand the important role of the heart in maintaining life activities.
