ANATOMY

Detailed explanation-1: -Balloons: Each balloon represents the lungs which inflate when air is rushed in (inhalation) and deflates when air is expelled (exhalation).

Detailed explanation-2: -The bell jar model As the rubber sheet is pulled down the volume of the jar increases, the pressure therefore decreases and air is drawn in through the glass tube inflating the balloons, which represent the lungs.

Detailed explanation-3: -Which parts of the model lung represent the lungs, chest cavity, rib cage, and diaphragm? (The small balloon inside the bottle represents the lung. The bottle represents the chest cavity and the rib cage. The plastic /balloon handle represents the diaphragm.)

Detailed explanation-4: -The balloons inside the bottle represent our lungs, and the balloon at the bottom of the bottle represents our diaphragm. As we can see with our model, when the diaphragm muscle stretches downward, air can move into the lungs.

Detailed explanation-5: -The balloon at the bottom works like your diaphragm-a strong muscle that expands and contracts to cause your lungs to fill with air and then empty out again. The movement of the balloon matches your breathing – when you breathe in, your lungs fill with air just like the balloon inside the bottle did.
