Question

Experiment on mechanism of breathing

Answer 1

Answer:

Experiment to demonstrate the action of the diaphragm during breathing

concept

Method-

Take a bell jar. Towards its rounded end, fix a 'Y' shaped glass tube and on the open ends of the two branches tie a balloon each.

On its open end, tie a thin rubber sheet. The cavity of the bell jar acts as the thoracic cavity, the "Y" shaped tube as the trachea that branches into bronchi and the rubber sheet as the diaphragm.

With this setup the demonstration of breathing is done.
