ELI5: Would you die if you injected water into your bloodstream?
gpt
Depends on how much water you injected. A small amount (a drop or so) probably won't kill you. A larger amount would cause your blood cells to rupture because the concentration of water inside and outside the cell would be different. Water would rush inside the cell and blow up the cell membrane. If you kept injecting water eventually enough cells would blow up that you'd die. Even assuming that the cells could survive blowing up, you'd still die from your cells not being able to perform certain functions which require exact salt and sugar concentrations in your blood.
