Electric heartbeat and circulation teaching model designed for clear, handson demonstration of circulation principles and the heartbeat cycle. Key benefits Vivid visualization: Electric operation with flashing lights and colorcoded components shows systemic circulation, pulmonary circulation, and the difference between arterial and venous blood, making abstract concepts easier to understand. Controlled demonstrations: Demonstration speed is adjustable by buttons, allowing instructors to slow down or speed up the cycle to match lesson pace and reinforce key points. Ready to mount: The model is fixed with stainless steel hooks, enabling straightforward hanging for classroom or lab display. Focused on learning: Periodic pulsation of myocardial valves is shown clearly to illustrate valve function and rhythm during the heartbeat cycle. Main features Electric model for continuous, realistic motion during demonstrations. Speed adjustment via buttons for precise control during teaching sessions. Stainless steel hooks for reliable, easy hanging. Colorful design with flashing lights to indicate circulation routes and blood color changes. Visual pulsation that demonstrates myocardial valve activity and the cyclic nature of the heartbeat. Practical applications Classroom demonstrations: Use during school biology or university anatomy lectures to show circulation pathways and the heartbeat cycle in real time. Laboratory and training sessions: Support instructorled practice in anatomy labs, workshops, or teacher training where controlled, repeatable demonstrations are required. Exhibit or study display: Mount on a wall or display area to provide a clear, continuously operating visual aid for group learning and review. How it helps Makes circulation and heartbeat cycles concrete and easier to grasp by combining motion, color change, and audible pacing with adjustable speed. Supports varied teaching styles by allowing instructors to pace demonstrations for different learning levels. Simple mounting and operation reduce setup time so more class time can be devoted to instruction and discussion. Specifications and performance Electricpowered model with button controls for adjustable demonstration speed. Fixed with stainless steel hooks for hanging. Colorcoded and equipped with flashing lights to display systemic and pulmonary circulation, arterial and venous blood, and myocardial valve pulsation. This model is designed for educational use where clear, repeatable visual demonstration of circulation and heartbeat principles is required.
