- water movement from the ____ to ____
- ______ dehydration
- manifestations: _____ dehydration, _______, ______ edema, ________, _________
treatment: __________ fluids
-high sodium in the blood vessels pulls water out of the _____ cells into the blood vessels, causing the cells to _____ which causes _______, ________, ________ and _____
