In the model that you built of the respiratory system what structures did the straws represent
In the model of the respiratory system, the straws may represent different structures depending on the specific design of the model. However, in a typical model, the straws can represent the bronchial tubes, which are the air passages that lead from the trachea (windpipe) into the lungs.
To build a model of the respiratory system using straws, you would need various lengths of straws. One long straw can be used to represent the trachea, which starts at the back of the throat and carries air into the chest. Then, you can attach shorter straws (representing the bronchial tubes) to the end of the trachea, branching out like tree branches, to symbolize the division of the airways within the lungs. Finally, you can attach small pieces of straws or use other materials to represent the alveoli, which are tiny air sacs located at the end of the bronchial tubes where gas exchange occurs.
It's important to note that there can be variations in the design of respiratory system models, and the specific structures represented by the straws may differ depending on the purpose and complexity of the model.
