In a constructed lung model, the diaphragm typically represents the muscle that facilitates breathing, while the balloon or elastic bag simulates the lung tissue that expands and contracts with airflow. The tube or straw represents the trachea and bronchi, allowing air to flow in and out of the model. Lastly, any additional components, such as a container for water, may illustrate the pleural cavity and the effects of pressure changes during respiration.
One
There are about 30,000 of them in each lung.
They are present in the lung surrounding the alveoli.
There are 10 bronchi in each lung.
If you prick the balloon in a lung model, it simulates a condition like a punctured lung or a collapsed lung. This can lead to air escaping from the lung space, causing a loss of pressure and potentially compromising the lung's ability to expand and contract properly.
In a constructed lung model, the balloon typically represents the lungs, demonstrating how they expand and contract during breathing. The plastic bottle serves as the thoracic cavity, providing a structure that mimics the rib cage. The straw functions as the trachea and bronchi, allowing air to flow in and out of the lung model. Finally, the diaphragm is often represented by a flexible material at the base, illustrating how its movement influences lung capacity and airflow.

Pleura is a double layered membrane surrounding each lung.

Trachea
Bronchi are the two tubes that branch off into each lung.
