    The layman's question here:

    Is there a need for the human blood circulatory system to have beating pulses to push blood? I read the article noted below about how there is an experiment within a human patient of an artificial heart that doesn't create a pulse. If the human heart functions like a gas piston engine and the dual turbine is like.... a turbine engine, then wouldn't this new replacement heart be limited to extreme rest/overexertion phase of muscular use? Do organs perform functions rhythmically to pulse rate and pressure?

    I don't think there would be a problem - the only thing that comes to mind as a potential problem is the nephron.

    Mother Nature sometimes has some nasty surprises. I see no problems yet, but I could imagine some. For example : we know that physical stress causes some tissues to strengthen. It would not surprise me at all to learn that the high pressure pulses are required to force arteries to grow in strength, and without those pulses, we might see arteries getting very weak, inviting aneurisms.

    I on the other hand see problems with that.

    The vascular system is build for the stretching motion of the pulse of the heart, it's used to keep the veins from clogging. If the veins and arteries no longer expand, they become stiff and rigid, and all sort of stuff will clog it up.

    On a second note, some processes in the cells are also driven by this, the moment the blood "stops" flowing in between beats, is for cells the time to release signalling proteins into the bloodstream.

    I can think of more problems then that. But let's stop at those two, haha.
    Growing up, i marveled at star-trek's science, and ignored the perfect society. Now, i try to ignore their science, and marvel at the society.

    Imagine, being able to create matter out of thin air, and not coming up with using drones for boarding hostile ships. Or using drones to defend your own ship. Heck, using drones to block energy attacks, counterattack or for surveillance. Unless, of course, they are nano-machines in your blood, which is a billion times more complex..

    .
    This is controlled by smooth muscle around the arteries and valves in the veins and is independent from the heart.

    I know, that stil applies, but the pressure difference will no longer PUSH on to it, as these muscles will only tighten it. It should be a 2 way street. Though i am happy you pointed that out, as i forget to mention that.
