Glu, GABA, dopamine (DA) and 5-hydroxytryptamine (5-HT) were all detected within STN extracellular fluid (Bevan et al., 2000; Martinez-Price and Geyer, 2002; Shen and Johnson, 2000).
Effects of supplemental rbST and MF cooling on total body water (TBW), extracellular fluid (ECF), plasma volume (PV), blood volume (BV) and hematocrit are shown in Table 4.
The SIADH paradigm also accounts for occurrences of EAH at moderate levels of fluid intake, as water retention before the onset of an escape from antidiuresis leads to weight increase with an expanded extracellular fluid volume.

The cell receives nutrition and excretes waste materials through a constant fluid exchange with extracellular fluid via a semipermeable membrane.
Vasopressin is released whenever serum osmolality is increased or when there is extracellular fluid volume depletion (independent of plasma osmolality).
Almost 99% of all the calcium in the body is stored in the bone, with only about 1% in the extracellular fluid and 0.1% in the intracellular fluid.
The osmolarity is 1900 mOsm/L, approximately six times that of extracellular fluid. It promotes shifting of fluid into the bowel lumen and increases the pressure gradient across an obstructive site.
During crisis, the dehydration of RBCs can take place, which could be a possible cause of sodium loss from the extracellular fluid into the intracellular fluid.

This body cavity is the largest compartment containing extracellular fluid, the coelomic fluid (CF).
When the body is in water balance, the osmolarity of intracellular and extracellular fluid compartments is the same, with a normal range of between 275-295m0smol/L.
