Answer 1

Answer:

JUST SOME EXTRA OBSERVATIONS :

• THE BALLOONS ARE THE LUNGS
• THE RUBBER SHEET IS ACTING LIKE DIAPHRAGM
• PLASTIC BOTTLE AS THE BODY
• AND THE TUBE IS ACTING LIKE THE WIND PIPE{TRACHEA+BRONCHI BOTH}

NOW THE WORKING:- (AS DEEP AS YOU REQUIRE)

WHEN THE DIAPHRAGM IS RESTING THE AIR GETS IN THE LUNGS, WHICH IS CALLED AS INHALATION, THE SAME IS SHOWN BY THE RUBBER SHEET AND THE BALLOONS. WHEN THE DIAPHRAGM TAKES ON THE UPWARD DOME SHAPE PUSHING LUNG, RESULTS IN PUSHING THE AIR INSIDE LUNG OUT, WHICH IS CALLED AS EXHALATION. SAME IS SHOWN IN THE SECOND FIGURE...

THIS PROCESS CONTINUES RHYTHMICALLY, INVOLUNTARILY AND LEADS IN BREATHING.
