1. During early dehydration, the serum osmolality may not show any significant changes. As dehydration continues, fluid is lost in greater quantities from the extracellular space than from the intracellular fluid (ICF) space. This results in an ECF (excess/deficit) _______________________

2. When dehydration is severe, the serum osmolality increases, causing water to leave the cells.

A severe ECF deficit can lead to an ICF (excess/deficit) __________________
