I know a little bit of lore, but not a whole lot (I just listen to lore channels at work lol). But the question occurred to me upon thinking about midichlorians. I recall hearing somewhere they connect to blood cells, but I know I’m losing my mind so maybe I just made that up somewhere
No. Midichlorians react to the presence of Force Sensitivity in living beings, but they are not the cause of it.
The Force is the Force. It is omnipresent in all things, both animate and inanimate, but biological beings are unique in that they form a kind of symbiotic relationship with it.
The midichlorians are present in the cells of Force Sensitive beings because they just really like being close to such a powerful conduit. if they were forcibly moved elsewhere, you would still not be able to feel the Force and your own cells would replace them over time anyway.
The force is definitely more than just the mechanics of biology. I can’t imagine a blood transfusion does anything. It shouldn’t connect you to the force any more than chopping off a Jedi’s arm and waving it around would.
And there are loads of inanimate objects strongly connected to the force: holocrons, kyber crystals, whatever materials are used to construct and paint Jedi temples, etc. Droids are too.
