Final answer:

The 'Bunch of Grapes' model represents alveoli in the lungs, facilitating gas exchange efficiently.


Explanation:

The 'Bunch of Grapes' model represents the alveoli in the lungs, which are tiny air sacs where gas exchange occurs. These alveoli resemble a bunch of grapes due to their small size and large number, facilitating efficient exchange of gases like oxygen and carbon dioxide.

The pathway of oxygen in the breathing system starts from the nose, travels through the trachea, enters the lungs, and finally reaches the alveoli where it diffuses into the bloodstream. From the bloodstream, oxygen is carried to cells throughout the body to support cellular functions.
