diaphragm
Yes, exhalation occurs when the diaphragm and muscles of the rib cage relax.
The Rib Cage, Sternum and the Diaphragm.
Your diaphragm expands, your rib cage goes up, and your lungs also expand. I learned this in science.
it is located in the upper abdomen to the right of the stomach and immediately below the diaphragm (the diaphragm is a set a muscles below the rib cage and lungs that help with breathing.)
It is called the Diaphragm, which is under the lungs and rib cage. ---- The Diaphragm is what moves the rib cage up and down when you breath in and out.

Inhaling.
The Rib Cage, Sternum and the Diaphragm.
These are the muscles that move the rib cage and they work together:Diaphragm (Prime mover of inhalation). If you need to breathe deeper you will use these:Scalenes (Elevate rib cage, assist in inhalation)Sternocleidomastoid (Elevate Rib Cage, assist in inhalation)Pectoralis minor (Elevate Rib Cage, assist in inhalation)External Intercostals (Elevate rib cage, assist in inhalation)Internal Intercostals (Depress, assist in exhalation)The diaphragm is under both voluntary control (holding your breath) and involuntary control (sleeping, reading)
When the diaphragm and muscles of the rib cage relax, the thoracic cavity becomes smaller. These changes occur during exhalation.
The diaphragm controls lung movement. The rib cage also contributes to this.
