Did you know that blood is poisonous to brain cells?
But that’s just weird.
Yes. Yes, it is.
If you look properly at the brain, you’d realise that there’s a barrier between the blood vessels and our actual brain cells. Nutrients can pass through the barrier, but not blood. If blood touches any brain cells, they die. That’s why strokes can be so dangerous.
Most strokes happen because a blood vessel (usually an artery) has been blocked and some parts of the brain can’t get any of the stuff they need, but some strokes happen because of a burst vessel. Something goes wrong, blood flows into the brain cells, brain cells die, a hole gets left behind, and certain problems arises.
Kinda weird how the very thing that you can’t live without is poison to your own brain, huh?
