What changes take place in the muscles of diaphragm during the process of inhalation and exhalation? Also give reason for these changes?

Asked by Topperlearning User 24th July 2017, 4:32 PM
Answered by Expert

During the process of inhalation, the muscles of diaphragm contract, diaphragm flattens and size of thoracic cavity increases so that large amount of air (oxygen) can enter into the lungs.

During the process of exhalation, the muscles of diaphragm relax, diaphragm is pushed upwards and the size of thoracic cavity is reduced so that results in release of air (carbon dioxide).
