The bell jar model of the lungs is a simple representation that helps illustrate how changes in pressure impact lung volume and air flow. It is useful for conceptualizing basic principles of lung mechanics, such as inspiration and expiration. Additionally, it can assist in understanding the relationship between pressure differentials and lung expansion.

What is bad about a bell jar model?
A bell jar model can create a closed system that isolates the subject from real-world interactions and influences, limiting the understanding of complex systems. It may oversimplify or distort the true dynamics at play, hindering the ability to make accurate predictions or understand the full picture. Additionally, a bell jar model can lead to a false sense of security or certainty in the results obtained within that isolated environment.
How do bell jar lungs work?
The bell jar is an airtight space. When the rubber diaphragram is pulled the volume of the space increases and air rushes into fill it, therefore expanding the balloons. When the diaphragram is released the volume of the space dcreases and the air in the balloons is pushed out. The balloons deflate.
What does the rubber sheet on bell jar do when pulled down?
When the rubber sheet on a bell jar is pulled down, it creates a vacuum seal between the bell jar and the surface it is placed on. This vacuum seal allows for the removal of air from within the bell jar when connected to a vacuum pump, creating a vacuum environment inside the jar.

How do you make a homemade apparatus to show how breathing of lungs occurs?
Refer to wikipedia for a diagram and description of how a bell jar works, and how it demonstrates effectively how breathing takes place.
Describe the bell in a bell jar with vacuum experiment?
A bell jar is a piece of laboratory equipment used for creating vacuums.[1] It can be similar in shape to a bell, and can be manufactured out of a variety of materials (ranging from glass to different types of metals). A bell jar is placed on a base which is vented to a hose fitting, which can be connected via a hose to a vacuum pump. By pumping the air out of the bell jar, a vacuum is formed.
