Plasma is the liquid component of blood. After allowing sufficient time for uniform distribution of the indicator throughout the compartment a plasma sample is collected.

Measurement of body fluids. Another way to measure body water is through dilution and equilibration using mass spectrometry which measures the abundance of water in breath samples from an individual. It is a thick fluid containing 55 blood 90 water and 8 proteins. Theoretically its possible to measure the size of each of the body fluid compartments by injecting substances that will stay in one compartment only the substance that attach to object. The major fluid compartments of the body electrolyte concentrations of body fluids are usually expressed in milliequivalents per liter meql a measure of the number of electrical charges in one liter of solution. This is estimated by measuring the volume of distribution of isotopes of water. The different types of body fluids include.
Rapid mixing of tritiated water throughout all compartments occurs during a 3 to 4 hour equilibration period. The indicator dilution method can be used to determine the size of body fluid compartments see chapter 14. One way to get an uncertain estimate is by calculation based on body weight and urine output. 222 total body water. A known amount of a substance the indicator which should be confined to the compartment of interest is administered. Tritium oxide tho is used because it is a weak beta emitter making it easy to measure in a liquid scintillation counter.
The main components of blood include.
