[Atherosclerosis Model]: Atherosclerosis is caused by infection of the artery wall. It makes the artery become tough and narrow, limit the blood flow inside the blood vessel. Therefore, smoking is the main reason that leading to arteriosclerosis [Comparative Model]: Through the model, people can clearly see the difference between smoking arterials and normal arterials, including color, shape and structure, making it easier for people to understand the impact of smoking on artery health [Teaching Display]: Arteries model can be placed on the display cabinet or on the desktop as a reference for teaching and learning. The anatomical model is an important auxiliary tool in medical teaching, which can be used to demonstrate and explain relevant knowledge [Healthy artery Model]: Artery is the blood vessel for bring the blood from the heart. Its blood vessel wall is very tough, which can control the blood quantity by expanding or shrinking [Application]: Human artery model is suitable for medical schools, hospitals, scientific research institutions and other places, for students, doctors and researchers
