When you Exhale, does your Rib Cage go; Up, Down, Stay the same, or, Out?

Report as

There are 2 ways to breathe, chest and diaphragm. Breathing with your diaphragm is actually healthier, and your rib cage doesn't move. Instead your stomach goes out when you inhale and in when you exhale.
Breathing with your chest, your ribs go out when you inhale and in when you exhale.

Now everyone who reads this Q is breathing to see what happens.
My chest goes up an out. I cannot see my ribs so I do not know about the ribs, but I would assume out and up as well.

The diaphragm contracts, causing air to fill the lungs. As the lungs expand, the ribs very slightly expand upward and outward, but overall there is only slight basic change to the skeletal structure.
Breathing is an active process - requiring the contraction of skeletal muscles. The primary muscles of respiration include the external intercostal muscles (located between the ribs) and the diaphragm (a sheet of muscle located between the thoracic & abdominal cavities).
The external intercostals plus the diaphragm contract to bring about inspiration:
Contraction of external intercostal muscles > elevation of ribs & sternum > increased front- to-back dimension of thoracic cavity > lowers air pressure in lungs > air moves into lungs
Contraction of diaphragm > diaphragm moves downward > increases vertical dimension of thoracic cavity > lowers air pressure in lungs > air moves into lungs.
