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. The intracellular fluid icf compartment is the system that includes all fluid enclosed in cells by their plasma membranes.
Distribution Of Total Body Water Tbw Within The Body
Body fluid compartments and their measurement. Two thirds of total body water is held within cells as intracellular fluid icf. Extracellular fluid ecf surrounds all cells 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 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. 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. Distribution of body fluids roughly 60 of the total body weight is water. 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 membranes.
Below we discuss how these compartments are defined the nature of their separating barrier and how much of the fluid volume each compartment contains in a healthy individual.
