Hemodynamic model of the heart for demonstration experiments in physics and biology lessons

The content of optional students' project activity aimed at creating a device for modeling the pumping function of the heart has been developed. The device is a liquid pump assembled from two medical syringes with a valve inside the piston and is intended for use in physics and biology classes. The difference and advantage of the proposed model from the previously developed one is that the proposed new design ensures hard synchronization of the work of the ventricle and atrium, which facilitates the demonstration of experiment.
