The reasons behind insisting on using cardiac anatomy model for teaching are profound and multiple, mainly reflected in the following aspects:

First, the anatomical model of the heart, with its intuitiveness and three-dimensional nature, provides students with an unparalleled learning experience. As one of the most complex organs of the human body, the heart has a fine structure and complex functions. It is often difficult for students to form a comprehensive and profound understanding only with the text description and two-dimensional images in books. The heart anatomy model can truly restore the three-dimensional shape of the heart, so that students can touch, observe, and even disassemble and reassemble, so as to feel every detail of the heart more intuitively and deepen the understanding of cardiac anatomy.

Secondly, the application of heart anatomy model in teaching is helpful to cultivate students' practical ability and spatial imagination ability. Medicine is a highly practical discipline, and doctors rely on an accurate understanding of anatomy during diagnosis and treatment. By operating the cardiac anatomy model, students can simulate surgical operations and observe pathological changes, so as to exercise their operational skills in practice and improve their ability to diagnose and treat heart diseases. At the same time, the three-dimensional form of the model also helps students to establish spatial concepts and cultivate spatial imagination, which is crucial for understanding complex cardiac structure and pathological changes.

In addition, the cardiac anatomy model is flexible and customizable in teaching. With the continuous development of medical technology and the constant change of teaching needs, the cardiac anatomy model is constantly updated and improved. Teachers can choose the appropriate model for teaching according to the teaching content and the actual needs of students. At the same time, some advanced models can also enable interactive functions, such as through touch screens or virtual reality technology, to give students a deeper understanding of the structure and function of the heart. This flexibility and customizability makes cardiac anatomy models an indispensable tool in medical teaching.

Finally, insisting on using the heart anatomy model for teaching is also a kind of respect and inheritance for traditional teaching methods. Although modern science and technology provide many new means and methods for medical teaching, the traditional teaching method still has its unique value. As one of the important tools in medical teaching, cardiac anatomy model has formed a mature teaching system and method after long-term practice test and continuous improvement. Adhering to this traditional teaching method not only helps to maintain the continuity and stability of medical teaching, but also helps to cultivate students' awe and sense of responsibility for the medical career.
