Let’s imagine that organs can be perfectly grown in a lab and installed into a body without any chance of rejection or other complications usually associated with organ transplant.
You, a perfectly healthy adult human, go to the doctor and have them put a second heart in your chest that is connected to the circulatory system with your original heart.
What would be the effects of this? Could it even be done in this hypothetical situation at all?
Even if they were physically separated you’d want them to pump in sync, to maximize the pressure. So having them share electrical signals is just the optimal setup for two hearts.
you want to maximize flow, not pressure. maximizing pressure is a great way to die of stroke.
Not absolute pressure, but pressure per unit of work (i.e., efficiency).
