Hemodynamics is a branch of fluid mechanics, which mainly studies the physiological process of circulatory system from the perspective of mechanics, and has a wide range of applications in medicine. The entity teaching model is made to help medical students master the knowledge of hemodynamics more easily and intuitively by showing them the phenomenon of laminar flow, turbulence and axial concentration of red blood cells.
