Procedure: 1. Hold up the bunch of grapes. Let the bunch of grapes represent the breathing system. 2. Within your group, locate the parts of the breathing system: the main stem as the trachea, the large branching stems as the bronchi, and all the little stems as the bronchioles. The individual grapes are the airsacs or alveoli. One by one, gently take out some of the grapes to expose more of the branching stems (bronchioles). Observe its structure. 3. 4. Trace the pathway of oxygen using the "Bunch of Grapes" model. Note that air moves from the nose (nasal cavity) and mouth (oral cavity) to the trachea, bronchi, bronchioles, and then into the alveoli (air sacs). The air we breathe carries the gas oxygen. When we breathe, the oxygen goes to the lungs. BRONCHI ALVEOLI TRACHEA BRONCHIOLES Figure 1. The bunch of grapes model of the breathing system

I can't solve it 3,5 you can't solve
Explanation:
A bunch of grapes as a breathing system then the outside part of the stem is the outside part also of the brochus/trachea etc. If you cut a section of it you will see the inner part, the middle of the circular section that you've been cut from the stem then that center must be the passage of the airways.
For the bunch of grapes the inner/middle part of stem is also the passage of nutrients to build a delicious grapes that is similar to your experimentation the air passage is the main component to make our alveoli function.
