Answer:
Complete answer:
During inhalation the diaphragm contracts causing expansion of the thoracic cavity. This gives a flattened appearance because of the enlarged diaphragm. Then, during expiration or exhalation the contracted diaphragm relaxes to reduce the volume of the thoracic cavity giving itself an arched appearance.
