How much do our organs move?

In addition to the heart and lungs, what's the extent and type of movement of our organs like the intestines, stomach, kidneys, liver, etc.?

Each organ has its own little sack, and that sack is embedded inside a larger sack, so imagine everything’s pretty organized on where it is based on the sack system, with tissue allowing for some movement (like a few inches in any direction temporarily) but still having central locations for everything. Also some organs are not intended to move, and when they do move that’s very very bad (like the brain). 

If you are asking about movement in terms of proper functionality. Organs that do filtering such as the liver or kidneys don’t move at all. The stomach and intestines move constantly, expanding and contracting with smooth muscles.
