on inhalation (breathing in) the main muscles used in respiration at rest are the diaphragm at the base of the chest and external intercostals between the ribs. On inhalation the muscles move the ribs and sternum to expand the chest stretching the lungs as they fill with air.
On exhalation (breathing out) which is mainly passive -the enlarged lungs recoil and shrink as the intercostals and diaphragm relax. Abdominal pressure pushing the diaphragm upwards to actively compress the lungs back to their resting volume.
