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?
You’d also have to solve the problems of them working with each other instead of against each other.
What happens to your blood pressure? Do they beat at the same time then how do you mitigate the pressure spike. You now have twice the capacity your blood vessels are meant to handle.
If they don’t beat at the same time how do you make sure blood does not just go back and forth between the hearts, but actually does something useful?
If they’re in series the pressure will increase, if they’re in parallel the flow would increase. Just have a pacemaker organ connected to both to time the pumps. You could reduce blood pressure but increase the amount of blood flowing, therefore less wear and tear on the hearts, arteries, organs, etc.
Not a hole Keisha. A VALVE.
