A family member is getting one next week. I know im looking at it wrong, but if you have 8 pints of blood and they add in more where does the extra blood go? Or do they take some out first?

Today transfusions are usually just the red blood cell component of blood, so its less about the added fluid volume and more about having more red blood cells.
But as for fluid volume, your blood vessels have muscle around them that allows them to become larger or smaller. So the total volume of blood can fluctuate somewhat without any issues just by opening up more vessels to make room. This happens all the time when you go from being dehydrated to hydrated as blood is mostly just water.
