When the lower ribs are stabilized and the central tendon of the diaphragm is mobile, a contraction brings the insertion ( central tendon ) towards the origins and pushes the lower cavity towards the pelvis, allowing the thoracic cavity to expand downward.

When the central tendon is stabilized and the lower ribs are mobile, a contraction lifts the origins ( ribs ) up towards the insertion ( central tendon ) which works in conjunction with other muscles to allow the ribs to slide and the thoracic cavity to expand laterally and upwards.
