To make a 3D model of the circulatory system that shows how fluid circulates

To make a 3D model of the circulatory system that shows how fluid circulates, you can follow a series of detailed steps. This project requires a little more complexity and use of specific materials, but here you have a complete guide: ### Materials Needed 1. **Support base**: It can be a wooden board or sturdy cardboard.. 2. **Transparent plastic tubes**: To represent the arteries and veins. 3. **small water pump**: Para simular el heart bombeando blood. 4. **Small tank or reservoir**: To store the fluid that will circulate. 5. **Red and blue dye**: To color the water and differentiate arteries and veins. 6. **clay, clay or 3D printing**: Para modelar el heart y otros órganos. 7. **Paints and brushes**: For details and finishes. 8. **Strong glue and hot silicone**: To assemble the pieces. 9. **Small check valves**: To ensure unidirectional flow. 10. **Air pump or a suitable power source**: To feed the water pump. 11. **Connector tubes and adapters**: To connect the tubes to the pump and tank. 12. **Some LED lights (optional)**: To highlight fluid flow. ### Steps to Follow 1. **Model Design and Preparation**: - Draw a diagram of the circulatory system on the support base. - Identifica la ubicación del heart, major arteries and veins. 2. **Modeling of the Heart and Organs**: - One plasticine, arcilla o una impresora 3D para crear un modelo del heart y otros órganos principales. - Paint and detail the organs for greater realism. 3. **Water Pump Installation**: - Place the water pump on the support base, making sure it is securely fastened. - Connect the water pump to the fluid reservoir (this will be the tank "blood"). 4. **Piping system (Arteries and Veins)**: - Connects clear plastic tubes from the pump (heart) to different parts of the body
