Care of Client With Fluids and Electrolytes Imbalance (Process of Movement Across The Membranes)
3. FLUID MOVEMENT BETWEEN EXTRACELLULAR AND INTRACELLULAR FLUID
Changes in the osmolality of the ECF alter the volume of the cells.
Water deficit occurs when an increased ECF osmolality pulls water out of cells until the two compartments have similar osmolality.
Decreased ECF osmolality is associated with water excess as the cells gain excess water.
