EXTRACELLULAR FLUID (ECF)
From NeuroRehab.wiki
SUMMARY
1. Think of ECF like an ‘internal sea’, a medium for exchange O2 & waste, crucial for cell function & survival.
2. ECF is iso-osmotic with ICF at osmotic equilibrium
3. ECF is best measured using inulin, a polysaccharide, MW5200
4. Transcellular water = that component of ECF that has been processed through cells into special compartments (aqueous humour, CSF, synovial fluid).
