in the model you built of the respiratory system, what structures did the straws represent

Answer 1

In a model of the respiratory system using straws, the straws typically represent the airways, including the trachea and bronchi, which are the passages through which air travels to and from the lungs. The larger, main straws could symbolize the trachea, while smaller straws could represent the bronchi and bronchioles, branching out into the lungs. The flexible nature of the straws can also mimic the flexibility of the respiratory system's tubes, allowing for airflow while reflecting the anatomical structure of the airways. This model can help illustrate how air is conducted and distributed throughout the respiratory system.
