Why do hospitals inject saline into your bloodstream instead of just water?
In: 110
Humans came from the sea. We carry the salty ocean water with us. So any fluid you put in your body should not change the salt level too much. Modern oceans have become saltier over time due to run-off. We only think of ourselves as pure land animals but we can only be on the land because we carry our ocean inside of us and we must constantly replenish the ocean in us.
