Which organ is responsible for raising the height of the right diaphragmatic dome?

Explanation:
The height of the right diaphragmatic dome is set by what sits directly beneath it. The liver fills a large area under the right hemidiaphragm and is dense enough that its size and position push the right dome upward, determining how high that portion of the diaphragm sits. The heart sits higher within the thorax but isn’t the main factor that elevates the right dome, and the stomach or spleen on the left don’t exert the same upward force on the right side. So, the liver is the organ responsible for raising the height of the right diaphragmatic dome.
