3D - 2

How do I build a 3D respiratory system model that works without me having to blow into it that uses a pump?

I need it to work using a pump that can pump water through the lunges and back a tube out the nose.The water needs to be able to go into ONE lung and change color so you are able to see that it is carbon dioxide.I need to know what kind of materials I need.The water (oxygen) needs to go through only one lung because the other is used to show the alveoli.the pump has to be able to push the water back up a tube (trachea) and out the nose.i dont want to use balloons or plastic bottles.I want my project to be able to open one lung and show the other lung full of alveoli.The model needs to be able to work with the flip of the pump switch.I would like to be able to have it work on its own without me having to touch anything except for the switch.what should i use as the body?i do not want to useany cardboard or balloons or bottles or rubber bands.i want it to be very high tech.it needs to be able to be done in two weeks.This is for a class project.This is a respiratory model that stands up.

1. You could make a realistic looking lung with sponge and tubing, sealed in plastic. If you saturated the sponge "lung" with ink, you could try the crayolla color bath tablets, then water emerging from the lungs would be colored. However, you would have a hard time getting the color out at the other end so the system would not be able to loop.
2. Among quadrupeds, the respiratory system generally includes tubes, such as the bronchi, used to carry air to the lungs, where gas exchange takes place. A diaphragm pulls air in and pushes it out. Respiratory systems of various types are found in a wide variety of organisms. Even trees have respiratory systems. In humans and other mammals, the respiratory system consists of the airways, the lungs, and the respiratory muscles that mediate the movement of air into and out of the body. Within the alveolar system of the lungs, molecules of oxygen and carbon dioxide are passively exchanged, by diffusion, between the gaseous environment and the blood. Thus, the respiratory system facilitates oxygenation of the blood with a concomitant removal of carbon dioxide and other gaseous metabolic wastes from the circulation. The system also helps to maintain the acid-base balance of the body through the efficient removal of carbon dioxide from the blood. The above is good detail about the respiratory system. so you can go out that of type of a vacuum pump type model. This may give good results.
