Hydraulic forces help to fill the heart

As a trainee, I was taught by my attendings that the circulatory system is based on hydraulic forces and I in turn have been teaching my students likewise for nearly a decade. Indeed, I even use the car brakes analogy in addition to Ohm's law and elements of fluidics (Poiseuille's law). I'm a bit perplexed on what is new here. :/
