The part of the human thorax represented are as follows: (i) Lungs; (ii) Diaphragm; (iii) Trachea (iv) Bronchi

(i) Balloon - Lungs

  • The movement of the balloons in the given model matches that with the movement of lungs during breathing.
  • During inhaling, the air enters the lungs. Likewise, the balloon inflates when air is filled in it.
  • During exhaling, the air leaves the lungs. Likewise, the balloon deflates when air is thrown out.

(ii) Rubber sheet - Diaphragm

  • When lungs are filled in with the air, the diaphragm expands to make space for this expansion.
  • Here also, the inflating of the balloon is facilitated by the rubber sheet, which makes space for the inflated balloons.

(iii) Tube A - Trachea

  • The air is taken to the lungs with the help of a pipe-like structure called the trachea.
  • Here, pipe A represents the trachea.

(iv) Tube B - Bronchi

  • Trachea branches into two bronchi to facilitate the gaseous exchange in the two lungs.
  • One bronchus reaches each lung.
  • Thus, pipe B represents bronchi.
