The constructed lung model is made up of several parts that represent different parts of the human respiratory system. The specific parts represented may vary depending on the model, but here are some common representations:
-
Plastic bottle: This represents the chest cavity or thoracic cavity in the human body, which houses the lungs and other respiratory organs.
-
Straws: These represent the bronchi, which are the two main branches that lead from the trachea (windpipe) to the lungs.
-
Balloons: These represent the lungs themselves. In some models, there may be two balloons to represent the left and right lungs.
-
Diaphragm: This is represented by a rubber sheet or balloon that is stretched across the bottom of the bottle. When the diaphragm contracts, it pulls down on the lungs and causes them to expand.
Its important to note that the specific parts represented may vary depending on the model, and some models may include additional parts or features.
