Imagine you and your buddy Carl went hiking on a hot day in the mountains. Carl ran out of water and was really
dehydrated. He wasn't doing well when you got back to the trailhead, so you called an ambulance to get him some help. After making sure that Carl was stable, the EMT administered 0.9% saline solution through an IV on him.
Draw and describe what happens to Carl's blood cells in the 0.9% saline solution?
