Question

the diaphragm contacts during the exhalation process true or false
​

Answer 1

False because during exhalation diaphragm returns to its original position.

Answer 2

During the exhalation process, the pressure in the lungs increases and the volume of the lungs also reduces due to contraction this forces the air out of the lungs.

This is achieved by the restoration of the upward curved bow like shape of the diaphragm which means that the diaphragm relaxes during exhalation.

So, the statement is false.
