Correct Answer

Explanation

The diaphragm is a dome-shaped muscle that separates the thoracic cavity from the abdominal cavity. When the diaphragm contracts, it flattens and increases the volume of the thoracic cavity. This expansion of the thoracic cavity occurs mainly in the anterior-posterior axis, as the radial muscles present in the diaphragm contract and flatten the dome shape of the muscle. This results in the expansion of the lungs and allows for inhalation of air.
