Body Fluid Compartments - Part 2
In order to have a solid understanding of physiological principles, it is essential that one understand the organization of body fluid compartments, as well as the composition of the fluids in these compartments. Test your understanding of body fluid compartments by taking this simple quiz.
(1)   What is the normal osmolarity (in mOsm/L) of the intracellular fluid?
(2)   What is the normal osmolarity (in mOsm/L) of the extracellular fluid?
(3)   What is the normal osmolarity (in mOsm/L) of tissue interstitial fluid?
(4)   What is the normal osmolarity (in mOsm/L) of plasma?
(5)   Approximately, what percentage of total body water is in the extracellular fluid compartment?
(6)   Approximately, what percentage of total body water is in the intracellular fluid compartment?
(7)   Approximately, what percentage of total body water is in the intravascular fluid compartment?
(8)   Plasma comprises approximately __________% of total body water volume.
(9)   In an average adult female (55 kg in weight; or ~120 lb), approximately what percentage of the total body weight is composed of water?
(10)   In an average adult male (70 kg in weight; or ~155 lb), approximately what percentage of the total body weight is composed of water?
