where is the connection between the muscles of the ventricles and the necessity of pushing the blood? and there is no push, the blood mostly falls in...

When I first learned this many years ago, what we now call "atria" were called "auricles." Somewhere along the way (and this happens a LOT with anatomical terms), the Powers-That-Be tweaked the definitions. The atria are now the actual pumping spaces, and the auricles are the side-pockets (which vary a great deal from species to species).
If you learned from a dated source, this would be confusing.
