The ultimate cause of death due to dehydration is a fluid/volume shift that causes structural changes to cells and cellular proteins. Which is the following correctly describes the steps that lead to this lethal fluid/volume shift? A extracellular osm.pressure increases.. which leads to an increase in total body water. Water then moves it of cells B a net water loss causes intracellular osm.-pressure to decrease. Water then moves out of cells C a net water loss causes extra cells osm.-pressure to decrease. Total body water increases and fluid moves and out of cells D a net water loss causes total body water to decrease and extracellular osm-pressure to increase. Water then moves down its concentration gradient (out of cells) into extracellular space E none of the above are correct
