So the more muscles one has the higher the total body water will be. Indicator dilution method depends upon law of conservation of mass. Total body water is 60 of body weight and is divided into various body fluid compartments. If the amount of the substance is known and the resulting concentration is measured the volume can be calculated. The total body water is divided into compartments and useful physiological insight and some measure of clinical predictability can be gained from this approach even though most of these fluid compartments do not exist as discrete real fluid collections. This is a simplified arabic illustration for the medical students if you have any questions please dont hesitate to contact me at fb.
The intracellular fluid is the fluid within the cells of the body. Body fluids can be discussed in terms of their specific fluid compartment a location that is largely separate from another compartment by some form of a physical barrier. The two main fluid compartments are the intracellular and extracellular compartments. The human body and even its individual body fluids may be conceptually divided into various fluid compartments which although not literally anatomic compartments do represent a real division in terms of how portions of the bodys water solutes and suspended elements are segregated. The intracellular fluid icf compartment is the system that includes all fluid enclosed in cells by their plasma membranes. Total mass of the indicator after distribution in the compartment is the same as the mass before distribution.
There are two main fluid compartments water occupies in the body. About two thirds is in the intracellular fluid compartment icf. Indicator properties disperses evenly throughout the compartment. Extracellular fluid compartment further. Fluid compartments are defined by their position relative to the cellular membrane of the cells that make up the bodys tissues. Body fluids can be discussed in terms of their specific fluid compartment a location that is largely separate from another compartment by some form of a physical barrier.
Intracellular fluid the intracellular fluid of the cytosol or intracellular fluid or cytoplasm is the fluid found inside cells. Body fluid compartments can be measured by dilution of a compound that distributes only in the space of interest. The intracellular fluid icf compartment is the system that includes all fluid enclosed in cells by their plasma membranes. In contrast skeletal muscle contains 75 water. Measurement of different body fluid compartments. These include intracellular fluid and extracellular fluid.
The indicator dilution principle is based on the definition of a concentration.
