Answer 2

The illustrated lung model makes use of plastic bottles, straws and, balloons to represent the respiratory system.

The upper part of the straw characterizes the trachea.

Explanation:

• The following are the construction materials used in the illustrated model of the human respiratory system.

                  1. The two balloons ⇒ lungs

                  2. The bottle ⇒ The chest cavity

                  3. The balloon that covers the bottom of the bottle ⇒ Diaphragm

• The inflation and deflation of the balloon demonstrate the breathing during respiration.
• When we breathe in, our lungs fill with air just like a balloon and we breathe out, it the balloon deflates.  
• When we pull down the balloon at the bottom of the bottle (diaphragm), it illustrates what takes place when the diaphragm shrinks and the respiratory muscles move outward.
