These are called alveoli.
The bronchi (or air passages) continually divide into smaller and smaller bronchi in the lungs, until they become bronchioles. The very smallest of the bronchioles end in a tiny sac or 'balloon' called alveoli.
The alveoli are surrounded by a dense network of capillaries which allows the exchange of gases between the lungs and the bloodstream.

A lung model with balloons works by simulating the expansion and contraction of the lungs during breathing. The balloons represent the lungs, and as air is pumped in and out of the balloons, they inflate and deflate to demonstrate how the lungs function. This model helps visualize the process of breathing and how the lungs take in oxygen and release carbon dioxide.

There's been less inflation.
Yes, it is possible to fly with balloons by using a hot air balloon or helium balloons, but flying with small party balloons is not feasible for human transportation.
Balloons and lungs both function as expandable structures that can hold air. When inflated, a balloon stretches to accommodate the air inside, similar to how lungs expand during inhalation to fill with air. Both can also contract: a balloon deflates when the air is released, and the lungs expel air during exhalation. Additionally, they both rely on the principles of air pressure and volume for their operation.

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.
The model lung with balloons can be used to demonstrate how the diaphragm and rib muscles work together to expand and contract the lungs, mimicking the process of inhaling and exhaling. As the balloons inflate and deflate, it shows how the lungs fill with air when we breathe in and release air when we breathe out. This hands-on demonstration helps visualize the mechanics of breathing in a simple and interactive way.
The branching tubes within the lungs end at small alveoli.
small air sacs in your lungs are alveoli (plural) they are where the air you breath in is stored
