In the model that you built of the respiratory system, what structures did the straws represent? the diaphragm the chest cavity and ribs the trachea and bronch the lungs

In the model that you built of the respiratory system, the structures that the straws likely represented are the trachea and bronchi. The trachea is the main airway that carries air from the mouth and nose to the lungs, and the bronchi are the two main branches of the trachea that lead to the lungs. Straws can be used to represent these structures because they are tube-like and can mimic the shape and function of the trachea and bronchi in the respiratory system.
