How to Make a Breathing System?

Published in Breathing System Model 3 mins read

Making a basic model of a breathing system can be done with everyday materials to understand how our lungs function.

Understanding the Components

According to a YouTube video titled "DIY Respiratory System! #lungs #respiratorysystem ...", the core components of a simple model are:

  • Lungs: Represented by two small balloons.
  • Diaphragm: Represented by the bottom of a container that moves up and down.
  • Container: Holds everything, allowing to see the action.

Steps to Make a Simple Breathing System Model

Here’s a step-by-step guide to creating a basic breathing system model:

  1. Gather Materials:

    • Two small balloons (the lungs)
    • A plastic bottle or a container with an open top
    • A sturdy material to use as a diaphragm (like a balloon, or rubber sheet)
    • Scissors
    • Tape or glue
    • A straw or tube (to connect the balloons)

  2. Prepare the Bottle/Container:

    • Cut the bottom off the plastic bottle or leave the top open if using a container.
    • This acts as the thoracic cavity containing the lungs and helps show the movement.

  3. Assemble the Lungs:

    • Attach a straw or tube to the opening of the two balloons with tape. This will allow air to move between the system.

  4. Position the Lungs:

    • Place the two assembled balloons inside the container or bottle, with the straw exiting the top.

  5. Create the Diaphragm:

    • Cut the rubber sheet (diaphragm) to slightly bigger than the bottom of the container.
    • Seal the container with the rubber sheet using glue or tape, ensuring it is airtight.

  6. Demonstrate Breathing:

    • Push the rubber sheet/balloon (diaphragm) up and down to simulate the diaphragm's movement.
    • As the diaphragm moves down, air should rush into the balloons (lungs), making them inflate. Conversely, when the diaphragm moves up, the balloons deflate.

How it Works

The video explains that when the diaphragm moves down, it creates space, which pulls air into the lungs to inflate them. When the diaphragm moves up, it pushes air out of the lungs. This movement of air in and out is what we call breathing.

Practical Insights and Solutions

  • Airtight Seal: To ensure the model works properly, make sure the seal around the diaphragm is airtight.
  • Observation: Observe the balloons inflating and deflating, mimicking the actual breathing process.
  • Troubleshooting: If the balloons aren't inflating or deflating, check for any leaks or obstructions in your setup.
