Miniature representation of the classic bell jar model demonstrating the relationship between the human diaphragm and lungs. Use this model to teach the concepts of pressure and volume and their importance in human respiration. This model is 3-1/4 x 2-3/4" and has a thick, durable vinyl diaphragm that resists tearing.

Use this small model to introduce and reinforce the concept of pressure as a driving force in respiration. The lungs (3" balloons) are housed in a hard plastic bell jar (3-1/4 x 2-3/4") representing the thoracic cavity. Unlike other models, the diaphragm is molded to fit securely on the bell jar without further attachments. It is also made of thick, durable vinyl that resists thinning and tearing over time.

Pull down on the diaphragm to decrease the pressure in the thoracic cavity and increase its volume. These changes cause higher-pressure atmospheric air to fill the lungs.

  • WARNING: CHOKING HAZARD - Children under 8 yrs. can choke or suffocate on uninflated or broken balloons. Adult supervision required. Keep uninflated balloons from children. Discard broken balloons at once.

How-To & Techniques

 
Rated 4 out of 5 by from Small, but effective. The model is quite small, but functions well. The diaphragm comes off to replace balloons (haven't had to, yet), and easily goes back on with a good seal. Wish it was bigger to show the whole class.

Rated 2 out of 5 by from Miniature lung function model is a no. I love Carolina products, but this one misses the mark. This model resembles the larger models found in the Human Body Systems Kit, but it not particularly user friendly. I tried one of them and found it clumsy to handle. I also do not trust the longevity of the 'bead' at the bottom. I will not be buying a class set.
