Project Proposal:
Construct a model that show how the circulatory system works.
Description of Model:
Functions It Will Perform:
Circulate oxygen-depleted blood from the heart to the lungs back to the heart (pulmonary circulation), and circulate oxygenated blood to organs throughout the body and back to the heart (systemic circulation). As the blood is pumped, it will provide the needed oxygen and nutrients from the blood to the various organs and body parts.
Materials Needed:
Construction Plan: Attach the end of the tubing to the spout of the Gatorade bottle or the end of the pump with hot glue. Circle the tubing and attach it to the body of the other Gatorade bottle. Attach another piece of tubing to the spout of the other Gatorade bottle and circle the tubing back to the body of the first Gatorade bottle. Just after the tubing starts in the systemic circulation and just before the systemic circulation tubing ends, attach another loop of tubing. Along the pulmonary and systemic circulation, attach small pieces of tubing representing capillaries to blow up balloons representing organs, the head, the arms, the lungs, and other body parts.
Biology/Chemistry/Physics Principles Used: In Physics, Newton’s Third Law of Motion says that for every force is an equal and opposite force. When the water bottle or pump is squeezed, an opposite force pushes the air out of the bottle through the tubing.
Special Needs: 1. Different sizes and colors of balloons to represent the lungs, the head, arms,
and other organs and body parts.
Unresolved Issues: In the pulmonary circulation, oxygen-depleted blood pumps out of the heart to the lungs, where it is oxygenated, and back to the heart. The blood goes blue to red. We cannot solve the issue of air automatically turning from blue to red. And same with the systemic circulation. Here the oxygenated blood travels out of the heart, to the body, and back to the heart as oxygen-depleted blood. Again, how can we make the air turn from red to blue automatically?
Construct a model that show how the circulatory system works.
Description of Model:
- Use 2 Gatorade bottles and tubing to simulate how the heart pumps blood through the body and lungs. The air pumped by the Gatorade bottles will pump air into balloons around the tubing, which represent the organs and other body parts.
- Using a handheld or recirculation pump to represent the heart, tubing to represent the arteries and veins, and balloons to represent the organs, we will simulate the pulmonary and systemic circulations.
Functions It Will Perform:
Circulate oxygen-depleted blood from the heart to the lungs back to the heart (pulmonary circulation), and circulate oxygenated blood to organs throughout the body and back to the heart (systemic circulation). As the blood is pumped, it will provide the needed oxygen and nutrients from the blood to the various organs and body parts.
