∙ 15y agoThe contraction (flattening) of the diaphragm, coupled with the outward movement of the ribs leads to an increase in the thoracic cavity volume (chest volume). An increase in volume decreases the pressure, and therefore air is forced into the lungs from outside.
Therefore the diaphragm aids in changing the volume and pressure of the thoracic cavity.

∙ 7y agoWhen you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. This increases the space in your chest cavity, into which your lungs expand. The intercostal muscles between your ribs also help enlarge the chest cavity.

The intercostal muscles between the ribs also relax to reduce the space in the chest cavity.

The intercostal muscles are located between the ribs. They play important roles in breathing. There are two sets of intercostal muscles, external and internal. The external intercostals contract during normal inspiration, causing the rib cage to expand out and up and thus increase the volume of the chest cavity. The internal intercostals are used during forced expiration only. When they contract, the rib cage pulled down and together, shrinking the volume of the chest cavity.
