The Army calls the first three of these the âRequirements. Determination Phase,â and the last two, the âResourcing Phase.â The Requirements. Determination Phase of the TAA process establishes the total number and mix of units. needed, in the view of the Army, to conform to the guidance issued by OSD.
The major division is between the intracellular and extracellular portions: Hence, if the sodium concentration goes up in your extracellular fluid, water will tend to leave your cells and move to make up the difference there.odium and Water (1) - Body compartments. The human body is approximately 50-60% water (on the higher end for men, on the lower end for women). This water is distributed in two major compartments-the intracellular fluid compartment and the extracellular fluid compartment, in a ratio of roughly 2:1.
Transcellular fluid is the portion of total body water contained within epithelial lined spaces. It is the smallest component of extracellular fluid, which also includes interstitial fluid and plasma.It is often not calculated as a fraction of the extracellular fluid, but it is about 2.5% of the total body water or 5% of extracellular fluid.Examples of this fluid are cerebrospinal fluid, ocular fluid and joint fluid.t is often not calculated as a fraction of the extracellular fluid, but it is about 2.5% of the total body water or 5% of extracellular fluid.
