Compartment volumes are measured by determining the volume of distribution of a tracer substance. 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.
Lecture 1 Body Fluid Compartments Volume Composition
Body fluid compartments and their measurement. The compartment volume is calculated as. The tracer concentration in that compartment is measured after allowing sufficient time for uniform distribution throughout the compartment. 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. 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 barrierthe intracellular fluid icf compartment is the system that includes all fluid enclosed in cells by their plasma membranesextracellular fluid ecf surrounds all cells in the body. The intracellular fluid icf compartment is the system that includes all fluid enclosed in cells by their plasma membranes.
Intracellular fluid compartment 28 liters inside 75 trillion cells of body constitutes 40 of body weight composition of cell fluids remarkably similar even in different animals ranging from most primitive micro organisms to humans. A known amount of a tracer is added to a compartment.
