In the model that you build of the respiratory system what structure did the straws represent

Answer 1

In a model of the respiratory system, straws typically represent the bronchi and bronchioles, which are the air passages that lead from the trachea (windpipe) into the lungs. These structures branch out into smaller tubes, similar to how straws can be connected or branched. The purpose of using straws is to demonstrate how air travels through the respiratory system, allowing for the visualization of air flow and the pathway of oxygen as it moves into the lungs and carbon dioxide out of the lungs. Additionally, the larger straw may represent the trachea itself, serving as the main airway.
