Designing a Heart Valve
Project History:
For this project we used the knowledge gained from our previous research and activities to then build our own heart model by choosing materials and testing them to see if they at all emulated properties of a real heart valve. We then built a prototype model that would demonstrate the action of blood pumping through a valve.

How it Works
1st picture: squeeze the purple bottle and water from the ice bottle is pulled up through the tube
2nd picture: on the top of the tube there is a flap which is closed when fluid flows through and open when fluid is not flowing through
3rd picture: the purpose of the balloon is to create pressure so the fluid can be pulled upthrough the straw (valve)

Reflection
Our model turned out to work pretty successfully. With the water bottle acting as the heart, we would squeeze it and from the ballon there would be enough pressure so that water would be pulled up through the tube and go through the flap and into the water bottle. We had a lack of some materials so we went out and got our own balloons and plastic water bottle to use. We found some plastic tubing and we decided that these would all be good materials to use to emulate a heart valve. The parameters of this project were difficult because we had to do a lot of research on our own to gain enough background knowledge about hearts. Through team work we were able to complete the task and build a successful heart model.
