I’m about to go to the hospital to receive 2 units of blood, because I’m dangerously low on something (red cells?) .
It’s not my first time, but I always wondered, how does the body have space for an extra litre of blood in your system? What happens to the veins? Do they just stretch out a bit to accommodate? Also, what about having too much of other stuff after this? Like plasma? I am so confused by how all of this works.
I do know that there must be a way for the body to balance itself out afterwards, as usually I need to urinate quite badly afterwards 😅
Please help make light of this, I am not looking forward to being stabbed again ( I have extremely hard veins to find) and I need the distraction, and the answer!
Thank you !

You’re essentially a balloon filled with blood. It’s bad if that pressure goes too high or too low.
