RESPIRATORY System
Here is a picture of a model
Project Proposal:
Description
BREATHING
We have a gallon water jug with the bottom cut off. There is a cut balloon attached to the bottom of the bottle to represent the flow of the air in and out. A strip of tape with an air-tight seal will have a straw attached in it. At the end of the straw, inside the jug, there will be two balloons that will inflate and deflate due to the balloon creating more air and less air inside the jug.
DIFFUSION
We will have a filter system to represent the diffusion of the oxygen from the muscles into the cells. We will use a filter and a DYE and water solution to show this.
Construction
BREATHING
DIFFUSION
Functions
BREATHING
The first model will represent the contracting and expanding of the lungs when a person breathes. The functions of the lungs is to get the Oxygen to your body for the ETC cycle. If we didn't not have the lungs oxygen wouldn't get to your body and you would keel over and die.
DIFFUSION
The diffusion gets the oxygen to the cells. To represent the filtering of oxygen and carbon dioxide. Also the diffusion of the oxygen through the capillaries.
Materials
BREATHING
3 gallon bottle
Duct tape
plastic tubing
T tube
Large Balloons
DIFFUSION
Filter system
Filter
DYE
Water
Biology/Physics/Chemistry Principles
BREATHING
The expansion and the contracting of the balloons demonstrates the conservation law of gas. Instead of pressure building up in the bottle the air releases out of the straw into the air. A principle of physics is the pressure differential. The gas goes into the bottle to match the pressure inside.
DIFFUSION
The dialysis paper will expel the waste (dye). This happens by the separation of colloidal particles from dissolved molecules. A biological principle used in the system is oxygen in the ETC system, if we didn't have this system we could not produce energy to power our body. Oxygen diffuses by concentration so when there is less in the cells it goes int to make the concentration the same on each sides.
Unresolved Issues
We have no unresolved issues everything has been figured out.

Reflection
1. What organ system are you modelling?
A. Respiratory System
2. What are the functions of your organ system called?
A. To collect oxygen and place it in the blood.
Discuss your model
1.What functions does your model demonstrate? How does it demonstrate each function?
A.The inhalation and exhalation of air and the diffusion of oxygen into the bloodstream.
2. What function of your organ system are not demonstrated by your model? If you had time and resources, how would you demonstrate these functions?
A. We didn’t represent the exhalation of the CO2 and if we had more time and resources we would 3D print working lungs from stem cells.
3. What scientific principles did you need to understand in order to build your model?
A. Air pressure and diffusion.
Discuss the design process
1.How did you come up with ideas?
A.We used google as a reference and modified those ideas with the materials we had available.
2.How did your group decide on the ideas/plan that resulted in your model?
A.We voted on which idea best represented the respiratory system.
3.What ideas were considered and then dismissed? Why were they dismissed?
A.We thought of combining the two projects and that wasn’t plausible.
4.What problems did you face in the design process and how did you solve them?
A.We didn’t have many problems except a leaky nozzle and we fixed that using duct tape.
5.How many times did you have to redesign, test, or approve?
A.1 time
Discuss Collaboration
1.Who did what in your group?
A.We all researched and built the project but Griffin also kept us on track and motivated.
2.How did each member of the group contribute? How did you decide who would do what?
A.We all built the model and divided the work equally.
Discuss Project Management
1.How did you communicate with each other about ideas and logistics of building the model?
A.We talked to each other in class.
2.How did you resolved disagreements?
A.We all worked together well.
Relate to the Real World
1.How could what you learned during this project, your model, the concepts used in your model or the design and building help process relate to a real life situation?
A.We learned to collaborate with each other and learn more about the respiratory system more than what we knew before.
Overall
I had a really good time on this project . I had a really good group and we all worked together really well. I enjoyed this project a lot. It was cool to make models because I want to be an engineer when I grow up so it was a really good experience.
