Lungs Model

thingiverse

Lungs Model Crafted with Creative Flair Using a Plastic Bottle, Two Red Balloons, and Two Flexible Tubes. The lower balloon functions as the diaphragm, a muscle that expands and contracts, causing lungs to fill with air and then empty out again. The movement of the red balloons mirrors breathing patterns: when inhaled, lungs fill with air due to the diaphragm's expansion, creating space for air to flow through bronchus (represented by joint pipes in our model). Conversely, during exhalation, the diaphragm contracts, pushing all air out of the lungs. Students can have fun creating a new face for this innovative model. For inspiration, we chose the popular character Doctor Culocane from a famous cartoonist and YouTuber: https://www.youtube.com/watch?v=mFQukpkgoSI Overview and Background Overview The lower balloon emulates the diaphragm, a muscle that expands and contracts, causing lungs to fill with air and then empty out again.

Create two small holes on the bottle cap. Insert the two red balloons into the cap holes. Insert two small pieces of flexible pipe into the holes, allowing air flow inside the balloons. Join the ends of the pipes with a 3D printed piece. Cut the top off the third balloon and attach it to the bottom of the plastic bottle. Secure it with a ring built using a 3D printer. Create a funny face for the model with students, print it out, and apply it to the top of the bottle.
