Body measurements

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. The intracellular fluid is the fluid within the cells of the body. Fluid compartments are defined by their position relative to the cellular membrane of the cells that make up the bodys tissues. The indicator dilution principle is based on the definition of a concentration. This is a simplified arabic illustration for the medical students if you have any questions please dont hesitate to contact me at fb. Total mass of the indicator after distribution in the compartment is the same as the mass before distribution.

Total body water is 60 of body weight and is divided into various body fluid compartments. The intracellular fluid icf compartment is the system that includes all fluid enclosed in cells by their plasma membranes. 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 two main fluid compartments are the intracellular and extracellular compartments. So the more muscles one has the higher the total body water will be. These include intracellular fluid and extracellular fluid.

There are two main fluid compartments water occupies in 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. Body fluid compartments can be measured by dilution of a compound that distributes only in the space of interest. Indicator properties disperses evenly throughout the compartment. Measurement of different body fluid compartments. Indicator dilution method depends upon law of conservation of mass.

Extracellular fluid compartment further. In contrast skeletal muscle contains 75 water. The intracellular fluid icf compartment is the system that includes all fluid enclosed in cells by their plasma membranes. 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. If the amount of the substance is known and the resulting concentration is measured the volume can be calculated.

About two thirds is in the intracellular fluid compartment icf.
